I've been saying this for two years. Donald Trump is a Manchurian President, a Russian agent groomed to elevate the standing of Russia and gut the USA's - which, believe it or not, was still higher to a lot of people abroad than any other country. Russia is 1.8% of the world economy's GDP, it could not thrive during the Cold War in democracy, and while the US's record to its allies is, to say the least, chequered and sometimes quite murderous, the Soviet imperium was apocalyptic.
There are many people now on the Left who don't see a great tragedy in what's happening today. All they see in today's events is that the US is finally getting the inevitable comeuppance it deserves. For the moment, fuck'em. There will be a time, probably not that far down the road, when we'll have to take them very seriously indeed, but until then, they're not the source of the problem because regardless of how they feel, there's only little bits here and there they can do to affect the outcome. Their responsibility for the current tragedy is not particularly mammoth.
The real responsibility is the real conservatives, not the authoritarian reactionaries, but the ones who just believe in change happening more slowly, and therefore should be particularly terrified by what an outrage this whole excursive flirt with totalitarianism is, and do nothing but re-up their bargains with the devil because democracy is less important than tax cuts, overturning Roe v. Wade, stopping political correctness, the thought that nothing can be true if liberals believe it, and the idea that the patriotism of liberals is somehow less than conservatives because we believe in taking the perspective of other people and nations into account. Fuck the leftists who said this was all inevitable and what we deserve, but God damn all you traditional Republicans straight to the southwest corner of Hell.
