Macron is pushing "four pillars" in his approach, which would keep the nuclear pact, but - as with the proposed new treaty he discussed with Trump - would also address Iran's long-term nuclear work, its regional military activity in Syria and Yemen, and its ballistic missile program, which Tehran insists is for defensive measures.
Macron argued that scrapping it now could send precisely the wrong message to North Korea, a regime that Trump's foreign policy team is trying to bring to the negotiating table over its own nuclear weapons program.
"If they restart their nuclear program, they will have bigger problems than they have ever had before", Trump said.
As Macron prepared to leave Washington on Wednesday evening, he was not optimistic that his attempts at persuasion had succeeded.
"There will be more discussions between the French president and the president of the USA and those discussions can build on the continued implementation of the Iranian nuclear agreement".
The proposal that Mr Macron put forward to his United States counterpart involves preserving the existing agreement on the first of "four pillars" of a future deal. "The nuclear agreement was negotiated with seven countries and the European Union and can't be renegotiated or replaced on a whim".
Speaking at a joint session of Congress at Capitol Hill here, Macron said, "A commercial war is not consistent with our mission, with our history, with our current commitments for global security". However, under the agreement, a nation can not submit its withdrawal until three years after it enters into force for that party - which was November 4, 2016, for the U.S. Therefore, Trump needs to wait until November 4, 2019, to formally request the nation's removal.
US Defense Secretary Jim Mattis on Thursday emphasized the value of certain aspects of the Iran nuclear agreement, even as US President Donald Trump considers pulling out of the 2015 deal, which he has attacked repeatedly and this week called "insane". "You are the one now who has to help preserve and reinvent it", Macron said.
Seemingly speaking directly to Mr Trump, the French President urged the United States not to retreat from its historic military role in world affairs in an address met with a standing ovation from U.S. lawmakers.

The investigation is still ongoing. "We believe the husband was in the area, believed he was meeting the other woman for dinner". On the 24 of April 2018, authorities discovered the bodies of two women inside the kitchen of a Lowrys Lane home.

The United States and Europe first need to agree on what a supplemental deal would look like.
"I like him a lot", Mr Trump explained to reporters and officials looking on.
"We wrote these rules. It can be tempting to us as a temporary remedy to our fears", Macron said. Not now. Not in five years.
Rathke noted that one line in particular from Macron - "Let us face it, there is no planet B" - got bipartisan applause.
"It is true to say that this agreement may not address all concerns and very important concerns", Macron said in his speech.
Following Mr Macron's address to the US Congress, the White House said Mr Trump had spoken to the young French leader by telephone.
Macron acknowledged this disagreement between the USA and France before Congress, but said that these are bound to happen "in all families". Let us not replicate past mistakes in the region. Western allies can not let nationalistic impulses take over and "undermine the liberal order we set after World War II".
Before heading home, Macron acknowledged he expected Trump to pull out of the deal, based on his long opposition to it.
