They know it’s bullshit. The United States in this instance is doing the largely correct thing. However historically that hasn’t always been the case. Were usually the ones attacking and destabilizing other countries. South America, Hawaii, the middle east, Korea, Vietnam and on and on. Anyone that opposed US homogene as pushed by wealthy oligarchic fascist throughout American history. Has historically met and unfortunate end.
Realistically in this instance Russia is much closer to what the United States has been historically. Than they are any Ally of leninist regimes. But to leninists. They are the enemy of their enemy and an ally of convenience. Because overall outside of World War II etc. The United States has been the biggest constant enemy to much the rest of the world.
