Oh, it was permanent. This is the end of the US Empire for sure and that isn't rebounding; but it's likely other things too. The day after Trump stole the election, BRICs more than doubled in members and continues to grow (and the "s" is "S" with the attacks on South Africa;) aside from the world planning to isolate the USA which the USA is actively working towards as well.
Making threats just buys a little time while greatly motivating the long term exit from the abusive relationship... Take the mess with China Trump started 1st term, those soybeans lost never came back, China permanently replaced most US sourcing and Biden couldn't do shit to restore things outside of self harm (which he wouldn't do.)
I'd not be surprised if we don't have another Pandemic; Obama prevented two of them in 8 years. Now we do even less to prevent them around the world.
Talk to some Gen Z. They think it's normal; clueless. The damage from 1st Trump is already permanent - he wasn't jailed and shunned so everything that happened is ok. The extreme gullibility of Americans has also been proven 10 fold; it has permanently emboldened what can be attempted in the future.
