I think the foundation might be stupid. Bcoz you need everyone to agree. And the EU Why not they become like more independent but still together. Like the BRICS nation

But i get ur point. Maybe EU need to be matured. And the best way to get matured is a crisis. So you have 1 threat to unite everyone Also only Trump is stitting on their head (accoding to me) bcoz US is as big as the whole of EU combined and Putin is 15 times the power of EU when it comes to millitary
