Europeans were perfectly happy to buy American tech und military exports, thus earning U.S. money and making EU technologically and politically dependent from the U.S. - it really was perfect for the U.S. But the US decided that it was actually a BAD DEAL and they wanted to extort even more money and dependence from EU. So now EU is investing in their own tech and military, thus reducing the amount of money US is get…
I don't understand why Europeans have to blame Trump for "spending a fair minimum on their own defense in the face of existential threats" or "investing domestically in technology".
These are things you always should have been doing.
