President Trump is leaving soon for France for a G7 summit that is likely to be dominated by the escalating conflict with Iran.

Trump will meet with French President Emmanuel Macron, among other European leaders, who he has squabbled with over trade, Ukraine and security since his return to office.

The U.S. president is also scheduled to met as a group and individually with key Middle Eastern leaders and attend a working session with Ukrainian President Volodymyr Zelenskyy and G7 leaders, said senior U.S. administration officials not authorized to speak publicly.

One official added that Trump will "meet with G7 leaders to address key issues of shared importance, including economic growth and development, supply chain resilience, illegal immigration and artificial intelligence."

But what was originally expected to be a meeting focused on separate economic and security issues has been overtaken by concerns over surging energy costs and differences over a geopolitical crisis that is exposing fractures among the world's leading democracies.

"There is no doubt Iran is going to dominate the agenda at Evian," Brett Bruen, who served at the National Security Council during the Obama administration. "It is going to be both a military and security challenge. It's a major economic challenge, but it's also a political challenge."

The bubbling tensions between the U.S. and its G7 allies over the war in Iran exploded into public view a few weeks ago when Trump announced the withdrawal of at least 5,000 U.S. troops from Germany - during a clash with the Europeans over their reluctance to support the U.S.-led war in Iran.
