The Reddit tier anti America FUD on this site never fails to get a chuckle out of me. Every single day the discussion here gets lower and lower quality.
Pulling out of agreements, unilaterally starting unnecessary wars (and then whining that nobody participates), screwing up the world economy and oil markets, threatening tariffs on a whim, threatening Greenland. Trying to push conservative values on the rest of the world (eg companies with inclusion policies get blacklisted)
And this distrust is not going to go away even when a sane government replaces him. The American people already elected Trump twice. It's very clear that another similar president can be elected at any moment. It's not just Trump, there's a whole movement behind him that's not going to go away, like the heritage Foundation. The long-term trust is gone. And it's not coming back unless something substantially changes in the US which is very doubtful.
Afghanistan too, the exuse was 9/11 but the Taliban was never proven to be involved, it was all Saudi Arabians. But SA is a "friendly" nation so they had to go after Afghanistan instead. Meanwhile Bin Laden was living comfortably in Pakistan.
And Iran was not close to a nuclear weapon. https://www.scientificamerican.com/article/iran-was-nowhere-... . It was just that Netanyahu had destroyed all he could of Gaza and needed another war to be able to stay in power.
Further back the Vietnam and Korea wars were unnecessary too, America had no business there. If they wanted to become communist that was their right. The only one I can consider justified in some way was the first gulf war, because Iraq did indeed invade Kuwait.
All Trump did was prove to Iran that they need a nuclear weapon to be safe. What would actually have worked (and did work) would have been guarantees. You know like the agreement Obama achieved and Trump trashed.
