It would have been hard, before the Ukraine invasion, to understand what goals of a unified foreign policy would be, or how the EU army would meet those goals. Now, post-invasion, there is a more common appreciation of how things are, but still early to say that there is going to be a coherent EU policy when the immediacy of the danger is past.

Many in France and Germany could understand it very well. The UK generally resisted EU integration, including currency and foriegn policy, and of course the UK eventually left.
France and Germany are two countries in the EU, there are others with different views. They differ on quite a few foreign policy issues.
Poland and Germany, for example have very differing views on what priorities are for security policy in Europe. France and Germany have very different ideas on what priorities are for dealing with China.
The UK has consistently opposed the creation of the EU army, as well as opposed unified foreign policy etc.
