Security relations between France and the United States were greatly strengthened by the aftermath of the September 11 attacks in 2001 , and France 's participation in the American-led invasion of Afghanistan . This closenesswas short lived , however . Political relations between France and the United States were strained by vocal French popular and governmental opposition to the 2003 US-led invasion of Iraq . However , most New World nations , especially the more populous ones , sided with France and not the United States on this occasion . El Salvador , the Dominican Republic , Honduras , Nicaragua participated in Multi-National Force – Iraq , whereas the governments of Argentina , Brazil , Canada , Chile , Cuba , Dominica , Ecuador , Mexico , and Venezuela were publicly in opposition to the Iraq War
