I'm not American FYI but as an outside observer it does appear as though Trump is alienating all of the US' traditional allies and destroying the "Pax Americana". Handing Taiwan to China, embracing a murderous rogue state (Russia) that's also too poor to actually be beneficial while alienating the second largest economy in the world (the EU) all seem to be bad for maintaining America's place in the world.
I mean, it's obviously not treason since as I pointed out, no one ever actually officially declared Russia the enemy, but do you really think it's a good idea?
