Trump was correct with such remarks as the overly expensive new headquarters for the bureaucracy called NATO, and beyond. To disrupt the status quo was considered "dangerous" by all those for whom the status quo was paying them very well indeed.
When we were legal residents of Germany, we met those who were clearly aware that the US was helping support Germany and were unsurprisingly expecting it to go on in perpetuity. Why not? Other people's money is easy to spend, and when other people's money is withdrawn, those who have been enjoying the gravy train get angry and insulted.
The phenomenon is EXACTLY the same here in the states. Gimme. Gimme. Gimme.
Even towards the end of the cold war, that is all that NATO had become. It's about all that most standing militaries become when you don't have a real large scale war against a peer to clear out the dead wood and take your country and economy down to basic essentials, like WWI for Europe and WWII for all of us.
