Any decent EU military needs a common EU foreign policy. Both of those need treaty changes. Also Macron says a lot about Europe, but when he got the opportunity for action tends to fall short. France was in a great position to lead on Ukraine aid, but did not perform that amazingly.

EDIT: EU ammo purchases for Ukraine have been launched and some EU military organizational work as well, such as EU missions in Mali, the Red Sea and some other places. Also some good cooperation such as Germany and Netherlands integrating their armies.
