"Ten days ago, President Trump was saying the United States of America had a duty to disengage from Syria", Macron said during a two-hour grilling on French television, broadcast days after his government joined the US and Britain in launching strikes against alleged Syrian regime chemical weapons facilities.
US, Britain and France said they only hit Syria's chemical weapons capabilities and that the strikes were not aimed at toppling Bashar al Assad's regime or intervening in the civil war.
"It was retaliation, not an act of war", Macron said in justifying the operation a day before the French parliament was set to debate it. Trump's new tweet seemed to backtrack from the bellicose one of Wednesday in which he suggested to Syria and its ally Russian Federation that a USA attack over the alleged chemical weapons assault on civilians was all but imminent.
'We convinced him it was necessary to stay, ' he added.
"Strikes by US, France and United Kingdom make it clear that Syrian regime together with Russia & Iran can not continue this human tragedy, at least not without cost. We convinced him that it was necessary to stay", Macron said, during a two-hour televised interview with several French media outlets.
"Ten days ago, President Trump was saying "the United States should withdraw from Syria".
"France will in no way allow an escalation or anything that would harm regional stability, but we cannot allow regimes that believe they can act with impunity to violate worldwide law in the worst possible way".
"The President has been clear that he wants USA forces to come home as quickly as possible".
"We are determined to completely crush ISIS and create the conditions that will prevent its return".
The French president nevertheless said he wanted to engage in dialogue with all parties involved, including Moscow, in order to find a political solution for Syria.
Macron, who had made the use of chemical weapons a "red line" not to be crossed, bemoaned Russia's use this week of its veto to block a UN Security Council resolution on setting up an investigation into the attack that would name those responsible.
The allies fired missiles early on Saturday at three chemical weapons facilities in Syria to punish the regime for the alleged attack on the town of Douma.
Haley said the joint military strike "put a heavy blow into their chemical weapons program, setting them back years" and reiterated that if Assad uses poison gas again, "the United States is locked and loaded".
The French leader will make a state visit to the U.S. next week and is scheduled to travel to Russian Federation next month.
Macron said it had also been France which convinced Trump that the strikes had to be limited to suspected chemical weapons sites.
