Before we went into Kosovo, Russia wasn’t all that buddy-buddy with any of them. They still have some contention with Red China about some eastern territory.
We have been pretty buddy-buddy with the ChiComs (if they stopped selling us stuff, how long would our supply chains hold up?), the Iranians (Obama’s sweet heart deal sending billions in cash and NOT shutting down nuke development), Hamas (we brokered the deal that allowed them to develop in the first place).
It doesn’t make Russia a good guy, but alliances with bad guys by itself may only be a pragmatic play. Our instigation to foment color revolutions may make some folks antsy enough to make their alliances where they can find them.
Our foreign policy over the last three decades has made more problems than it has fixed.
Nonsense, those are Russia’s buddies and nothing changes, and when they are involved in wars, Russia helps them, and vice versa, you have seen it since perhaps before you were born but at least all your life and you are seeing it now, those countries have an enduring relationship and underlying commonality with Russia.
