In a speech to a joint meeting of Congress, Macron called on American lawmakers to construct a "new breed of multilateralism" in the face of urgent global threats - from climate change to terrorism. It doesn't address Iran's ballistic missile program or Iran's support for armed groups in places like Yemen or Syria. In Moscow, the Kremlin said there can be "no alternative" to the current deal with Iran. But addressing a joint meeting of Congress - an honor granted only occasionally to leaders of close United States allies - Macron confronted his differences with Trump head-on.
"And Donald Trump, really, he can not keep his hands off this guy", Kimmel said before showing television clips of affectionate embraces between the pair.

"It's insane, it's ridiculous, it should haven ever been made".
Trump seemed to backtrack on an earlier decision to withdraw USA forces from Syria, when he stressed on Tuesday that it was important not to allow Iran grow its influence in the region. "It was a bad deal".
The French president acknowledged that Trump had campaigned against the deal, yet he seemed to appeal to Trump's instinctive desire to hatch something big, outdoing his predecessors, by pressing him to renegotiate instead of scrapping it. Over the past few days, the behavior of the two world leaders has left hope for a French-American alliance.
Trump has described the 2015 accord, under which Iran agreed to curb its nuclear activities in return for the lifting of economic sanctions, as the worst deal ever negotiated and has threatened to wreck it by reimposing U.S. penalties next month unless the three European allies agree to fix its "flaws".
The two presidents had literally embraced each other, repeatedly talking up their much-vaunted friendship during the trip, but in his speech to Congress Macron rigorously pushed back against Trump's trade, climate and non-proliferation policies. The US sanctions will resume unless Trump issues fresh "waivers" to suspend them on May 12.
Mr Macron told Congress he was confident the United States will rejoin the climate agreement in the future.
Near the end of his three-day state visit, Mr Macron told USA media that while he did not know specifically what Mr Trump will decide, he believes the U.S. leader "will get rid of this deal on his own, for domestic reasons".
"We need free and fair trade, for sure".
Mr Trump has been a fierce opponent of the July 2015 agreement signed by Iran and worldwide powers. The 2014-15 talks by the U.S., Iran, Russia, China and European powers brought an end to a years-long crisis as Iran enriched uranium amid fears it would seek a nuclear bomb.
Macron also reiterated his plan to expand the nuclear deal with Iran to include provisions for restraining Tehran's influence in the Middle East. I hear these concerns, but we must find a smooth transition to a low-carbon economy.
As Macron prepared to leave Washington on Wednesday evening, he was not optimistic that his attempts at persuasion had succeeded.
In the spotlight of a speech to the US Congress, Macron was courteous but firm, deferential but resolute as he traced the lines of profound division between himself and Trump on key world issues: climate change, trade and the Iran nuclear deal. "You can play with fear and anger for a time", he said, adding, "Anger only freezes and weakens us".
We can choose isolationism, withdrawal and nationalism, this is an option. "What Macron was saying yesterday sounded new, because he explained the problem differently", said Behnam Ben Taleblu, a research fellow at the Foundation for Defense of Democracies, a Washington think tank that is hawkish on Iran.
