25th August 2026
When Russia launched its full-scale invasion of Ukraine in February 2022, the response across much of Europe was remarkably united. There was widespread sympathy for the Ukrainian people, anger at Russia's invasion and a determination that Ukraine should not simply be left to face a much larger military power alone.
Governments introduced sanctions, supplied weapons and provided financial and humanitarian assistance on a scale that few people could have imagined before the war began.
Four and a half years later, that support has not disappeared. In some respects, Europe is actually taking on a greater responsibility for Ukraine than it did in the early stages of the war. But something important has changed. The question being asked across Europe is becoming less about whether Ukraine should be supported and increasingly about how long the support can continue, how much it will cost and what the eventual end to the war should look like.
That distinction matters for Britain as well as for the European Union because the UK is now committing substantial sums of its own money while European governments are having to contemplate a much greater long-term defence commitment.
The scale of the European response is considerable. On 24 August, the European Union approved a further €6.1 billion for Ukrainian defence, taking previously approved EU defence assistance to €16 billion, of which €8.35 billion had already been disbursed. The latest money is intended for areas including air defence, missiles, ammunition and radar systems.
This is happening at the same time as American support has become much less predictable. The result is that Europe increasingly finds itself carrying a greater proportion of the responsibility for sustaining Ukraine.
Britain is part of that effort. The UK Government says total British support since Russia's full-scale invasion has reached £25 billion, including £16 billion in military assistance and up to £5.6 billion in non-military support. Britain has also committed itself to providing £3 billion a year in military assistance for as long as it takes.
Those figures are large enough to make the war a significant item in Britain's long-term defence and foreign-policy calculations. But they also need to be understood properly. Not every pound described as "support" is simply handed over to the Ukrainian Government as cash. Some is military equipment, some is financial assistance and some represents guarantees or financing mechanisms.
Nevertheless, the commitment is real, and it is continuing.
The question, therefore, is not whether Britain and Europe are supporting Ukraine. They clearly are. The more interesting question is whether public opinion will remain sufficiently supportive as the financial and military commitment continues year after year.
Europe has not turned its back on Ukraine
The evidence available at present does not support the idea that European populations have simply become tired of Ukraine and want their governments to walk away.
A YouGov survey conducted across Western European countries in February 2026 found that Denmark and Britain had the strongest support for continuing assistance until Russia withdraws from Ukraine. Forty-nine per cent of Danes and 46% of Britons took that position.
That is significant because the war has now lasted for years rather than months. Yet nearly half of the British public surveyed still believed the West should continue supporting Ukraine even if doing so meant the war and its effects lasted longer.
Elsewhere, however, the mood is different.
In France, Germany and Spain, the largest group in the same YouGov survey preferred encouraging a negotiated peace, even if that meant Russia retaining some Ukrainian territory. In Italy, 56% took that position.
It would be a mistake to interpret that as European support collapsing. There is a crucial difference between wanting Ukraine to be supported and wanting the fighting to continue indefinitely.
A person can believe that Russia was wrong to invade Ukraine, believe that Ukraine has a right to defend itself and still believe that eventually there has to be a negotiated settlement.
That may actually become one of the most important political distinctions as the war continues.
The British position is relatively strong
Britain appears to be towards the more determined end of European public opinion.
A separate YouGov survey published at the end of 2025 found that 70% of Britons said they wanted Ukraine to win the war and cared a great or fair amount about that outcome. The comparable figures were 66% in Spain, 65% in Poland, 54% in Germany, 40% in France and only 33% in Italy.
Those differences are important.
They demonstrate that there is no single European public opinion on Ukraine.
Countries closer geographically to Russia, such as Poland and the Baltic states, understandably have a very different perception of the threat from countries further west. Poland's experience of history also makes Russian military expansion particularly sensitive.
For countries such as Germany and Italy, meanwhile, the domestic economic consequences and the desire for an eventual negotiated settlement appear to have greater influence on public opinion.
Britain occupies an interesting position because it is geographically removed from the immediate battlefield but has traditionally regarded European security as a major strategic concern. Successive British governments have also viewed support for Ukraine as part of Britain's wider role within NATO and Europe.
The current Government has made clear that this policy is continuing. Prime Minister Andy Burnham's visit to Kyiv on 24 August was accompanied by further defence commitments, including assistance intended to strengthen Ukraine's ability to produce its own missiles. Britain has also been developing cooperation with Ukraine on artificial intelligence and battlefield technology.
That represents something considerably more substantial than humanitarian assistance.
Britain is becoming involved in the longer-term development of Ukraine's defence capability.
But support for Ukraine does not mean unlimited support for war
This is where political debate can become misleading.
Someone who says Britain should support Ukraine does not necessarily mean Britain should provide whatever Ukraine requests for as long as the war continues.
Likewise, somebody who believes that negotiations are eventually necessary is not necessarily arguing that Russia should be allowed to take whatever territory it wants.
The public debate can sometimes turn these positions into two opposing camps when the reality is much more complicated.
The YouGov research provides an excellent example. Britons and Danes were more likely than people in several other Western European countries to favour continuing support until Russia withdraws. But elsewhere there was a stronger desire for negotiations.
That may reflect a natural change in public psychology.
At the beginning of the invasion, the immediate question was whether Ukraine could survive.
Years later, people are asking what the endgame is.
That is a perfectly reasonable question for taxpayers to ask.
The cost becomes increasingly important
For Britain, £3 billion a year in military assistance is not an insignificant sum.
It is not necessarily money that could simply be transferred into schools, hospitals or council budgets if it were not being spent on Ukraine. Defence spending is part of a much larger national-security calculation.
Nevertheless, every pound of public money has an opportunity cost.
The same is true across Europe.
Governments are now trying to increase defence spending at precisely the time when they are already under pressure from ageing populations, healthcare costs, housing shortages, infrastructure requirements and demands for public services.
The war has therefore created a difficult political equation.
European governments are effectively saying that supporting Ukraine is itself an investment in European security.
The argument is that allowing Russia to defeat Ukraine could create a much more dangerous European security environment and potentially require considerably greater expenditure on defence in the future.
That is not an unreasonable argument.
But it still has to be explained to voters.
People cannot simply be expected to accept increasingly large commitments because politicians say they are necessary.
The American factor makes the problem more serious
For much of the war, Europe could rely upon the United States to provide enormous quantities of military assistance.
That assumption is no longer as safe as it once was.
The consequence is that European countries are having to think about whether they can collectively provide the weapons, ammunition, air defence systems and financial support that Ukraine requires.
The Kiel Institute's Ukraine Support Tracker is particularly useful because it measures military, financial and humanitarian assistance from 41 countries and allows comparisons between donors. Its latest assessments show that European countries have maintained military support at a high level even as the American contribution has become less certain.
This represents a fundamental change.
Europe is no longer simply supporting Ukraine alongside America.
It increasingly has to ask whether Europe itself can sustain Ukraine.
That is a much larger strategic commitment.
And that is where taxpayers eventually enter the argument
The difficulty for governments is that foreign policy can enjoy considerable public support until people begin to see a direct connection between the policy and their own household finances.
Someone may be perfectly happy to say that Britain should support Ukraine when asked a general question.
That same person might be less enthusiastic if asked whether they would accept higher taxes, reduced public spending elsewhere or slower improvements in public services to maintain that support.
This isn't hypocrisy.
It is the normal difficulty governments face when turning broad principles into actual budgets.
People can support an objective while disagreeing about how much they should personally have to pay to achieve it.
That is why the next phase of the Ukraine debate could become considerably more difficult than the first.
The war has already changed Europe's defence thinking
There is also another side to the expenditure which is sometimes overlooked.
Europe is not simply sending money abroad and receiving nothing in return.
Countries are rebuilding their own defence industries, expanding ammunition production and investing in drones, missiles, air defence and other technologies.
Some of that expenditure will remain within European economies and support European jobs and manufacturing.
The war has also demonstrated how rapidly military technology is changing. Ukraine's experience with drones, electronic warfare and battlefield artificial intelligence has become extremely valuable to other countries.
Britain's new cooperation with Ukraine over battlefield data and artificial intelligence is an example of this emerging relationship.
In that sense, the relationship is becoming two-way.
Ukraine is receiving military assistance, while European countries are learning from a country that has experienced modern warfare on an enormous scale.
But there is a danger of becoming trapped by the commitment
The longer a war lasts, the more difficult it becomes for governments to change direction.
Money has been spent.
Weapons have been supplied.
Promises have been made.
Alliances have been formed.
Politicians have publicly declared their commitment.
Eventually, changing course can become politically difficult because it can be portrayed as abandoning Ukraine or rewarding Russian aggression.
That creates a danger of policy momentum.
A decision that made sense in 2022 may not necessarily be the right decision in 2027 or 2028.
Circumstances change.
Russia's military position can change. Ukraine's military position can change. American policy can change. European defence capabilities can change. Public opinion can change.
Governments therefore need to be able to reassess their policies without automatically being accused of abandoning their principles.
Britain has an especially interesting balancing act
Britain has traditionally tried to position itself as one of Europe's strongest supporters of Ukraine.
That gives it influence.
It also gives Britain responsibilities.
If the United States reduces its involvement further, Britain cannot simply say that Europe should take responsibility while assuming that somebody else will provide the leadership.
The current Government appears to recognise that. The latest announcements from Kyiv show Britain continuing to position itself at the centre of European support for Ukraine.
But leadership also means asking difficult questions.
How much should Britain spend?
For how long?
What should the ultimate objective be?
How should Ukraine's security be guaranteed after a ceasefire?
How much of Europe's defence burden should Britain carry?
And perhaps most importantly, what happens if the war continues for another three years?
These are not questions that can be answered simply by saying "as long as it takes".
"As long as it takes" is a political commitment, but it isn't a budget.
Europe faces the same dilemma
The European Union's latest €6.1 billion defence package demonstrates that there is still a willingness to put substantial resources behind Ukraine.
But Europe also has to finance its own military forces.
It has to deal with energy costs, ageing populations, public services, infrastructure and economic competitiveness.
The European public may therefore eventually ask a very straightforward question:
How much of our national wealth should be devoted to defending Ukraine, and how much should be devoted to dealing with problems at home?
There is no easy answer.
The argument that supporting Ukraine protects Europe is persuasive, particularly to countries close to Russia.
But the argument also needs to be measured against the economic reality faced by ordinary households.
The most revealing change may be in what Europeans want the end to look like
This is perhaps the most important conclusion from the polling.
There is still substantial European support for Ukraine.
But support for Ukraine and support for an indefinite war are not the same thing.
The February YouGov figures show that Britain and Denmark remain relatively determined to continue supporting Ukraine until Russia withdraws, while France, Germany, Spain and particularly Italy show greater preference for negotiations.
That tells us that the European debate is gradually moving from the question "Whose side are you on?" to a much harder question:
"What would a realistic and acceptable peace actually look like?"
That question has no easy answer.
If Ukraine is forced to surrender territory without meaningful security guarantees, Russia could conclude that military aggression has succeeded.
If Ukraine is supported indefinitely in an attempt to recover every inch of territory, the war could continue for years at enormous human and financial cost.
Between those two positions lies an extremely difficult diplomatic territory.
The public may ultimately demand an answer
For now, European governments still have considerable room for manoeuvre because public support remains relatively strong.
But governments should not confuse that with unlimited patience.
A war entering its fifth year is different from a war that began four months ago.
A £3 billion annual British commitment is different from an emergency package.
A European defence system increasingly designed around the assumption that America may not always be there is different from the NATO arrangements that existed before the invasion.
The political landscape is therefore changing even though the fundamental sympathy for Ukraine remains.
And perhaps that is the most important point for Britain and the rest of Europe.
The question is no longer whether Europe supports Ukraine. The evidence shows that, broadly speaking, it does. The question is whether Europe can maintain that support financially, militarily and politically for as long as the war may last — while also persuading its own citizens that the price is justified.
For Britain, that means being honest about the £25 billion already committed and the £3 billion-a-year military commitment that lies ahead.
For the European Union, it means explaining why billions more are being allocated to Ukraine at the same time as governments are asking their own populations to accept greater defence spending and difficult choices over domestic budgets.
And for voters, it means recognising that there may be no painless option.
Abandoning Ukraine could carry a security cost.
Continuing the war carries a financial and human cost.
Negotiating a settlement could require compromises that many people find unacceptable.
The idea that there is a simple solution has probably disappeared.
What Europe now needs is something more difficult: a long-term strategy that explains not only how Ukraine is to be supported, but what Europe ultimately wants that support to achieve.
Because after four and a half years, the public is entitled to ask not simply "Are we still supporting Ukraine?"
It is reasonable to ask - "What are we trying to achieve, how much will it cost, and how do we know when we have succeeded?"
