Moscow has done us the favor of demonstrating that NATO is still needed, that Ukraine was right to seek allies, and Moscow has succeeded in uniting Ukrainians in a way Kiev never could.
The Russians weren't and aren't under any obligation to put up with US-funded biolabs with deadly pathogens in them on their borders or us heavily-arming Ukraine. If China or Russia were doing all that in Mexico, we sure as hell wouldn't tolerate it.
Nor do they have sit back and tolerate revolutions that we foment that led to an eight-year war in Donbass and the persecution of the ethnically Russian population in Ukraine. We've been funding and training neo-Nazis and encouraging them to wipe the ethnically Russian population in eastern Ukraine.
All that turned Ukraine into a honey hole for the Big Guy and our corrupt political class and their donors.
Our foreign policy is corrupt and wicked.
