That's not quite accurate. France did not reply to an act of war from an allied nation (turkey is part of nato). The turkish navy had a radar lock on a French ship. It is not easy to know if a radar lock is guiding a missile or not: in general it is assumed to be the case and the locked ship will fire in response before being hit. Erdogan is playing with fire with such tactic, and did similar things in the air between turkish f16 and greek air force, even suggesting to find a way to shoot down a greek jet in a way where the pilot could eject.
