21st October 2026
Ukraine and Russia continue to fight over territory and security, while the United States and Iran remain locked in a dangerous confrontation. Both conflicts are showing the limits of military power, and the consequences reach far beyond the battlefield.
There is a growing sense that two of the world's most dangerous conflicts have become trapped in a cycle of fighting, retaliation and unsuccessful diplomacy. Neither appears close to achieving all its objectives, yet neither has found a settlement it is willing to accept.
The war between Russia and Ukraine has continued for more than four years since Russia's full-scale invasion in February 2022. Meanwhile, the conflict involving Iran, the United States and Israel has created a separate crisis, with the future of the Strait of Hormuz threatening to affect energy supplies and prices around the world.
The circumstances are different, but an uncomfortable question connects them: what happens when neither side can secure a decisive victory, yet neither is prepared to compromise?
Ukraine and Russia: a war of endurance
The conflict in Ukraine illustrates how a war can continue long after the prospect of a quick military victory has faded.
Russia retains occupied Ukrainian territory and continues to press its military campaign. Ukraine, despite enormous damage to its infrastructure and economy, continues to resist and strike targets inside Russia, including oil and energy facilities.
Both sides are attempting to weaken the other's ability to sustain the war. Russia has repeatedly attacked Ukrainian electricity and energy infrastructure, while Ukrainian strikes on Russian facilities seek to disrupt fuel production and supplies that help sustain the Russian economy and military.
This has created a war of endurance. The outcome depends not only on developments at the front but also on manpower, ammunition, industrial capacity, economic resilience and the willingness of foreign governments to continue providing assistance.
For Ukraine, the challenge is to defend its territory and independence without exhausting the resources needed to maintain a functioning country. For Russia, the question is whether its military and economic pressure can eventually force Kyiv to accept terms that it has so far rejected.
Neither objective is straightforward.
Diplomacy offers movement, but not yet peace
There are renewed diplomatic efforts. On 20 October, Ukrainian President Volodymyr Zelensky met US envoy Steve Witkoff and European leaders in Oslo. Witkoff was expected to meet Russian President Vladimir Putin on 21 October, with discussions intended to advance a possible peace framework.
The proposals under discussion include security guarantees for Ukraine, economic recovery and wider European security arrangements. However, the fundamental disputes remain unresolved. These include the future of occupied territory, Ukraine's ability to defend itself and the terms under which Russia might agree to stop fighting.
President Donald Trump has pressed Kyiv to reach a settlement, arguing that Russia holds an advantage on the battlefield. Ukraine, meanwhile, has expressed concern about the reliability of American military support and the risk that a settlement could leave it vulnerable to another invasion.
These are not minor differences that can be settled simply by bringing leaders around a table.
A ceasefire could stop the immediate loss of life, but it would not automatically settle the question of borders or provide lasting security. A peace agreement would need arrangements that the parties could realistically implement and monitor.
The danger is that negotiations produce temporary pauses while attacks continue, leaving the underlying conflict unresolved.
Iran and the United States: pressure without a settlement
The confrontation involving Iran and the United States presents a different problem.
The conflict began with US and Israeli strikes against Iran in February 2026. Subsequent attempts to secure a lasting settlement have struggled over the nuclear programme, sanctions, security guarantees and control of shipping through the Strait of Hormuz.
That waterway is crucial to the global economy. Before the conflict, roughly one-fifth of global oil and liquefied natural gas trade passed through it.
Iran has offered proposals for reopening the strait, but these come with conditions, including demands relating to the US blockade, sanctions and the cessation of hostilities. Washington, in turn, wants the nuclear question addressed rather than allowing the shipping issue to be settled in isolation.
Each side is therefore trying to use its strongest bargaining instrument.
The United States can apply military and economic pressure. Iran can threaten regional security and disrupt a vital shipping route. Neither form of leverage guarantees that the other side will accept its demands.
Reuters reported on 20 October that Iranian officials expected negotiations to remain stalled and were preparing for the possibility of renewed US and Israeli attacks. Tehran also appeared reluctant to make concessions that could be presented as a political victory for President Trump.
This illustrates a central problem in the conflict: the two governments do not appear to trust one another sufficiently to make the first major concession.
Iran fears that concessions might leave it exposed to further military action. Washington fears that a settlement which leaves Iran with substantial nuclear capabilities or control over shipping would fail to achieve its objectives.
The result is a dangerous stand-off in which the economic costs continue to mount while diplomacy struggles to make progress.
The cost of continuing without winning
Wars are often judged by territory gained or lost, military targets destroyed and the balance of power between the combatants. But prolonged conflicts also impose costs that accumulate far beyond the battlefield.
In Ukraine, the destruction of homes, electricity networks and industrial facilities undermines the country's ability to recover even if fighting eventually stops. Russia also faces the continuing costs of military operations, sanctions and the diversion of resources away from other economic priorities.
In the Middle East, the disruption of shipping and the risk of further attacks have direct consequences for energy markets.
On 21 October, Reuters reported that Brent crude had risen to $110.38 a barrel amid concerns about supply disruption and heightened risks to maritime shipping. The price movement demonstrated how quickly fears about the conflict can feed into the cost of energy.
Higher oil prices do not remain confined to the energy industry. They can increase the cost of road transport, aviation, food distribution, manufacturing and heating. Businesses may pass some of these costs to customers, while households face pressure on their budgets.
For Britain, this is particularly concerning because the country is exposed to international energy prices even when much of its energy is produced domestically.
For households in rural Scotland, the impact can be especially difficult. People who rely on heating oil cannot necessarily benefit when wholesale gas prices fall, and deliveries may become more expensive when oil markets are unsettled. Farmers, hauliers and other businesses also face higher fuel costs that can eventually feed through into food and other prices.
A prolonged conflict could therefore contribute to inflation at a time when households and public services are already under pressure.
Could one war influence the other?
The two conflicts are not directly linked in the sense that a settlement in one would automatically end the other. Their strategic circumstances are different, and the parties have different objectives.
However, they compete for international attention, diplomatic resources, military supplies and political capital.
The United States must consider its commitments in Europe alongside its military posture in the Middle East. European governments must weigh support for Ukraine against their own defence requirements and the economic consequences of instability in the Gulf.
Energy prices add another complication. A prolonged crisis around Hormuz can increase the political pressure on Western governments to seek a rapid settlement, while also creating disagreements about what concessions are acceptable.
The conflicts can therefore affect each other's wider environment even without being formally connected.
There is also a danger that leaders who feel unable to demonstrate progress may intensify military action to improve their bargaining position. Such a strategy can backfire. An attack intended to force negotiations may instead provoke retaliation and make compromise more difficult.
Equally, domestic political pressure can encourage leaders to accept arrangements they might previously have rejected. That possibility is one reason not to assume that the present deadlocks will continue indefinitely.
Three possible ways forward
There are three broad possibilities for both conflicts.
The first is a negotiated pause. A ceasefire could reduce immediate casualties and economic damage, even if the difficult political questions remain unresolved. Such an arrangement would be valuable, but it would require monitoring and a credible process for dealing with violations.
The second is continued attrition. Neither side achieves a decisive result, but fighting continues because each believes that time will improve its position. This could mean years of intermittent attacks, damaged infrastructure and mounting economic costs.
The third is escalation. A major military setback, a breakdown in negotiations or a serious incident could prompt renewed and more extensive attacks. That might change the balance of pressure, but it could also widen the conflicts and make a negotiated settlement harder to achieve.
There is no reliable timetable for either war to end. Nor is there sufficient evidence to conclude that either conflict must continue indefinitely.
What matters is whether the parties move beyond statements of willingness to negotiate and begin accepting practical compromises.
The world cannot afford endless deadlock
The most troubling aspect of the two conflicts is not simply that peace remains elusive. It is that the costs of continuing are borne by people who have little influence over the decisions being made.
Ukrainian civilians face attacks and the destruction of essential services. People across the Middle East live with the danger of renewed fighting. Elsewhere, households and businesses pay more for energy, transport and goods because the consequences of conflict travel through international markets.
There are reasons to watch the latest diplomatic initiatives carefully, particularly the discussions concerning Ukraine and the proposals for reopening the Strait of Hormuz. But progress should be measured by concrete outcomes, not optimistic statements following meetings.
A lasting settlement requires more than an announcement. It requires arrangements that address the security concerns at the heart of each conflict and give the parties reasons to comply.
For now, both wars show the dangers of a prolonged stand-off. Military pressure has not removed the need for compromise, while diplomacy has yet to bridge the differences that keep the fighting going.
The question is no longer simply which side can inflict the greatest damage. It is whether the leaders involved can recognise that continuing to fight may cost more than any realistic outcome can justify.
Until that point is reached, the world may have to live with a deeply uncomfortable prospect: conflicts that are too costly to sustain, too difficult to win decisively, and still too politically complicated to end.
