Remember in 2016 when Republican types were adamant that Hillary wouldn't be tough enough on Putin, and that Liberals were Communists? And that the Liberals would let Russia do whatever it wanted?
And now those same Republicans are outspoken against helping Ukraine, and want to let Russia just have it. Their preferred candidate wants to dismantle the organization of countries that stands as the United front against Russian expansion. Working deliberately and blatantly toward Putin's interests isn't a problem to them at all.
Back then, I thought that if there was a single (decent) principle they actually stand for, that would have been it. Apparently I was wrong.
