It is good that Macron is aggressive towards Putin. It is a sharp change from the 1930's when France was timid towards Hitler. However, Ukraine doesn't have the ability to retake Crimea. If France enters the war, perhaps. This is better. The UN should propose to Putin and Zelensky that Russia be permitted to occupy territory it seized from Ukraine before the February 2022 invasion although the land would legally belong to Ukraine. Russia must withdraw from all land it seized after the invasion. NATO membership will remain as it is. The UN will be obligated to defend Ukraine if Russia invades again.
