President Donald Trump arrived in Geneva, Switzerland, on Monday ahead of the G7 summit, just one day after announcing an agreement aimed at ending the U.S. war with Iran.

The gathering of G7 leaders in France is expected to center on the ongoing Iran conflict, the Russia-Ukraine war, and other major international challenges.

Trump is scheduled to spend two days at the Group of Seven summit in the resort town of Evian-les-Bains, where both the Iran war and Russia’s invasion of Ukraine are expected to dominate discussions.

After beginning military action against Iran on Feb. 28, Trump has criticized European allies for failing to do enough to support U.S. objectives in the conflict.

Taking a swipe at British Prime Minister Keir Starmer, Trump said in the spring: “This is not Winston Churchill that we’re dealing with.”

European leaders, meanwhile, have pushed back, arguing Trump did not consult them before launching a war they believe could have been avoided.

French President Emmanuel Macron, who is hosting the summit, has called Trump’s military campaign against Iran “outside the framework of international law.”

Despite the tensions, Trump and other G7 leaders are expected to meet with Middle Eastern officials as he continues efforts toward a final peace agreement with Iran.

On Tuesday, Trump and fellow leaders will meet with Ukrainian President Volodymyr Zelenskyy to discuss possible paths toward ending the war under conditions they consider fair.

During a tense Oval Office meeting last year, Trump famously told Zelenskyy he “doesn’t have the cards,” urging him to accept a ceasefire. Since then, Ukraine’s military has strengthened its position against Russia through the use of advanced drones that have challenged Russian forces.

Analysts, European officials, and some Republican lawmakers say Zelenskyy now holds a stronger position than he did in 2025. Ukraine’s battlefield resilience has given Trump greater leverage to pressure Russian President Vladimir Putin to withdraw forces and end the war, they argue. The key question is whether Trump will act on that leverage.

“The Russians seem to be on their back foot,” said William Taylor, a former U.S. ambassador to Ukraine who is now with the Atlantic Council think tank.

Asked what Trump might say during the G7 gathering, Sen. Lindsey Graham, R-S.C., told NBC News: “He’s going to vent about their lack of support in Iran. And I’m hoping he’ll reset and re-engage in Ukraine-Russia. I hope he will understand that Ukraine is more than holding their own and now is the time put pressure on Putin to get this thing over with.”

One unpredictable factor at any Trump summit appearance is his mood. He is traveling to Evian directly after the Ultimate Fighting Championship event he organized on the White House grounds, which he had eagerly looked forward to attending.

Trump announced Sunday that he had reached a breakthrough in the Iran war, writing on his social media platform that a “deal” with Iran had been reached and that the strategically important Strait of Hormuz shipping route would reopen without Iran imposing a transit fee. That was the situation before the conflict began. The agreement’s durability will depend largely on whether Iran eventually moves toward developing a nuclear weapon.

Even if Trump arrives at the summit feeling optimistic, previous meetings with Western leaders have sometimes frustrated him. During a 2018 G7 meeting in his first term, Trump refused to sign the joint statement and criticized host Canadian Prime Minister Justin Trudeau as “very dishonest and weak.”

The following year, Trump questioned whether the G7 was still worthwhile, according to a CNN report.

This year, Macron is attempting to prevent another clash among leaders.

France delayed the summit by one day so Trump would not have to miss the UFC event, which took place around the time of his 80th birthday.

After the summit concludes, Trump will travel at Macron’s invitation to the Palace of Versailles for a private dinner with the French president.

“President Macron extended this private invitation for him to go to Versailles for this extravagant dinner, knowing that you know President Trump is one to enjoy the pomp and circumstance for an invitation that doesn’t sound like it’s been extended” to other world leaders, said Ned Price, a former State Department spokesman in Joe Biden’s administration.

Still, disagreements built up over the past year have created lasting distrust. Trump entered his second term suggesting Canada could become the 51st state and alarmed European leaders by threatening to take control of Greenland, a semi-autonomous territory of Denmark.

The two wars are another major source of friction, with leaders on both sides of the Atlantic accusing each other of failing to deliver what is needed.

European governments, concerned about a stronger Russia, have united in blaming Putin for the conflict and say Ukraine’s independence must be protected. Before the summit, a Macron aide told reporters that France wants members to agree on continuing support for Ukraine and does not want Kyiv forced to surrender territory to Russia.

Trump, however, has taken a less committed stance, at times criticizing Zelenskyy for refusing compromises that could quickly end the fighting. Trump’s repeated position is that the war must end as soon as possible. European leaders worry that his desire for a deal could lead to Russia gaining territory it does not currently control and that belongs to Ukraine.

“We need the war to end. We’re happy to have that happen, however possible,” a senior Trump administration official told reporters in a briefing last week.

For Trump, Europe’s hesitation to support the Iran operation has reinforced his belief that U.S. allies may not stand with Washington when needed.

“The paradox is the U.S. is telling us in Europe that we need to do more in Iran,” a European Union official, speaking on condition of anonymity told NBC. “And there are a lot of Europeans who’ve said the U.S. has left us alone with Ukraine. It goes both ways.”

Ahead of the summit, Putin and Zelenskyy separately called Trump to congratulate him on his birthday. Both leaders also raised the war, presenting arguments that could influence Trump as he meets with allies near Lake Geneva.

Zelenskyy said he discussed battlefield developments and “how our position has strengthened.”

Putin, meanwhile, praised Trump’s determination and resilience.

“The Russian president did not hide his respect for Donald Trump’s fighting qualities, his ability to take a hit, successfully overcome obstacles, and persistently achieve his goals,” a Russian read-out of the nearly hourlong call said.
