Besides, why can't their own friends in Russia and China feed them? Why is it American job to even literally feed the enemy?

Because it's in the interests of the Americans to do it.

While the Russians filmed themselves giving a medal for "denazification" in Mariupol to a smiling guy with Nazi insignia on his uniform. A member of Rusich, a Russian Nordic Pagan Hitlerite group.

OK, so you're not actually questioning the fact that nearly all Ukrainian soldiers appear to have Nazi insignia, tattoos, Bandera worship, etc. - just an is quoque.

Note that I don't care about their Nazi insignia. Only insofar as it shows that the regimes in the West are hypocrites, but so much was obvious already.

"World's villains" had to wait for Trump to begin sending any weapons at all. Go and check what and how much had been delivered yourself.

They pressured Trump with Russiagate to send offensive weapons to Ukraine. And apparently enough to make Lindsey Graham say that "2017 will be the year of offense" and Adam Schiff that "we send weapons to Ukraine so that we fight them over there so we don't have to fight them over here". And you're surprised that Russia does not tolerate this? It's open warmongering.

Russian artillery in Chechnya retired to using shells from the 1960s and 1950s with a ridicalous dud rate (like 1 in 3) because they shot themselves dry of anything remotely new.

OK, so Russia is not a threat to anyone. So no need for the constant warmongering or any sort of support for the Banderistas.
