Maybe they were never really allies to begin with, and have waited for Europe to become complacent enough to put down the hammer in our weakest moment.
Only a fool would expect America to come to their aid now, and we'd better hide our oil/minerals lest we get a double dose of dictator-flavoured freedom...
I mean, I think you can at least understand why directly interfering with the domestic politics of a representative democracy might be challenging.
And the Europeans are helping. Trump is not getting the straight forward quick foreign policy wins that he was chasing. Europe is going to keep sticking their "European peacekeeper" (however you want to characterize it) proposal into the Ukraine mix, and Putin is going to have a hard time swallowing that deal.
When the EU tariffs come, you can bet that EU is going to try to make it sting as much as possible.
But ultimately it's up to Americans to make the best of these opportunities.
