When did our timeline diverge from real history to an alternative history scenario written by a chinese nationalist...

Despite all this, the US fails all the time. They didn't lose in Vietnam because they were militarily outmatched, or flee from Afghanistan because taliban rethoric was too hard to debunk. No, their people eventually get fed up with being fucked like a sunbday whore and strike at the ruling party until they're unelectable for 60 years.

There is losing an invasion of some faraway country that could never directly threaten you anyways, then there's failing a war against a country next to you that can then occupy you and rape your population both literally and figuratively. The later will never happen to them

No less destructive, their closest comparison the soviet union collapsed after a failed invasion of afghanistan. The US has already had a civil war and never fixed the underlaying disunity that sparked it in the first place.

This doesn't take into account the fact that services (which are about to get tariff'd by the EU) are a major factor in US GDP; the US is still the largest consumer market in the world. These imports are goods that Amerilards consume to maintain their gluttonous lifestyles. If goods become unaffordable then the American standard of living will plummet, regardless of the proportion of GDP imports make up.

Trump's tarrifs will only make the American economy stronger in the long run
Russia will inevitably get what it wants in Ukraine, including a large population of Ukrainians and normalized trade with the US without unprecedented economic growth.
Europe will be stuck in the corner jarring it's dick as China smirks in the background
