"We have complete worldwide legitimacy to act in this framework", Macron said in an interview broadcast by BFM TV, RMC radio and Mediapart online news.
"We convinced him it was necessary to stay for the long term".
"We have not declared war on the regime of Bashar al-Assad", Macron said in a television interview, a day after France joined the United States and Britain in launching strikes.
Commenting further on the issue, Macron said that the Western strikes had split Turks from Russian Federation in Syria, as Ankara has approved the attack.
Speaking to USA media, Ms Haley defended the air strikes, warning that if action had not been taken, the United States could also become a target of chemical attacks. We will try to make it better.

European Union Commission President Jean-Claude Juncker said: "The worldwide community has the responsibility to identify and hold accountable those responsible of any attack with chemical weapons". Stoltenberg said: "Before the attack took place last night, North Atlantic Treaty Organisation allies exhausted all other possible ways to address this issue to the U.N. Security Council but ... were blocked by Russian Federation ... This was not the first time that the Syrian regime has used chemical weapons against civilians but it must be the last". "I am not saying that the attacks ... solved all problems but compared to the alternative to do nothing, this was the right thing to do".
"We support the fact that our U.S., United Kingdom and French allies took on responsibility in this way as permanent members of the U.N. Security Council". He said the allies had clear proof there had been a chemical attack in the town of Douma near Damascus on 7 April and that the Syrian government was responsible.
Macron's comments come after U.S. Ambassador to the United Nations Nikki Haley said on Sunday that the United States would not pull its troops out of Syria until its goals were accomplished.
After the US, France and Britain launched missile strikes on the country over an alleged chemical gas attack, the French president noted that Western top priority is preparing "a long-term political alternative which will allow a transition in a constitutional framework".
"They have not used chlorine themselves but they have methodically built the worldwide community's inability to act through diplomatic channels to stop the use of chemical weapons", he said.
