They are. They know where this is headed. Whoever comes after Trump will need to play catch up and kiss a lot of ass. Europe is starting to take the steps forward without the US by their side as it's becoming clear it could be an option.

That does not bode well for the US's long-term future; neither having a seat at the table nor for their economy.

We might be starting to see them reset back to pre-WW economic boom. Europe was just fine without them before and if they no longer want to offer the thing that boosted their economy back then, then nations will move on and economics will adjust over a couple decades.

Everything the US offers is available elsewhere and with alternative paths. Their military and intelligence has always been their bargaining chip—well, it was England's intelligence, but they gave it all over to the US and trained them as payment for assisting on the Western Front of WW2. Along with some territories...

Point is, in very simple terms. Imagine the world without the US; now imagine the US without the world.

I think a lot of modern day Americans don't understand how dependent on globalisation they are. To start losing stability there could be like watching a breeze hit a house of cards.

The US saying, "I'm sorry I turned my back. Please forgive me." is a lot more likely than all of Europe and some more nations saying, "We need you. Please don't go."

And if there's one thing Europe has gotten good at over a history extending far beyond US history, it's working as a powerful single organism. Their only notable conflicts—in context—are when they're responding to or revolting against one to two tyrants that got too cocky, like a cancer trying to destroy the rest. They're used to checking tall poppey syndrome, whether it red, purple, or in this case, orange.

Europe won't let Ukraine fall and the US will be in the history books as the powerful entity that ran away. They haven't won a war since helping out in Europe over half a century ago anyway.
