Unlike to end well for whom? What a scummy article, it basically calls for 4th reich, fearmongering with Russia, China, Iran. If USA fucks off, the entire reason while EU is hostile to those countries disappears in the first place. Author probably don’t even believe USA will fuck off, and he’s correct in that, but still use the classic boogeyman to scare people in EU to fork even more cash for MIC. How convenient it is to write prophecies backwards.
Unlikely to end well for the current Atlanticist political establishment that sucks on the US teat in order to exist. The whole article is basically preparing the public for the austerity that’s going to come in order to ramp up military spending. All that said, I do think that the US will leave Europe to hang as it shifts focus on Asia. This was gonna happen regardless of who won, but it will be happening much more in the open under Trump.
There is nothing wrong with expecting rich, 1st world, countries to pay for their own defense. The US has been subsidizing them, and their generous social benefits in turn, for too long.
The other option is to just not make enemies in the east, and learn to coexist with the rest of humanity.
