I have my popcorn ready.
All Trump did in his previous presidency was appoint crazier and crazier people and fall out with them and replace them within months. Sometimes weeks. The fallout with Elon Musk will be particularly amusing.
The EU stopping trusting the USA to support them is well overdue. The USA never cared a bit about the EU or, in fact, any European country. Actually, any other country. They were ready to do business with Hitler all the way up until Pearl Harbour was bombed. They would have done busines readily with an Aryan Europe without blinking. The USA stopped having a moral compass a long time ago, and it has been a decadent post-Empire for a while.
Europe and the rest of the World should start behaving like independent, sovereign states and treat the USA as what it is now: a decaying, albeit still powerful country who spends a lot of money in the military and likes to meddle (with catastrophic consequences) in other people's countries, that now may finally start behaving like an inward-looking decadent empire and stop treating other countries like their minions. I for one am looking forward to stopping taking the USA as the example for "the West", and right now trust countries such as China more than I trust the USA. China may have a government and attitude very different to my preferences, but at least have a very long History and a way of dealing I can understand, and a stable behaviour. If you play by their rules, you get the results you expect. The USA is completely unstable, egotistical and untrustable right now, and in my opinion will continue to be for the foreseeable future.
At least we have the USA ruled by someone they, this time, voted for without a doubt (or without as much doubt we can have that their elections have not actually been rigged), and I am a firm believer that every country has the government they deserve. I do feel for women, imigrants, LGTB community and all the ones who will be royally fucked, but as I said, they have voted for this and it's their mess to deal with.
