Exactly! NATO is in bad condition (Problem), because of Europeans. Not us. Biggest threat of NATO are the members Germany and France. You will see it in the future.
Again, read what Trump said about European NATO members. And remember what US did to his 'allies' in Afghanistan and Syria. Bombed the infrastructur of German energy supply (war case). But we are the problem.
Dont worry, EU army will not come soon. Remember Macron speech about China and US. One week later, we have seen riots all over France. US will prevent any move in that direction.
