This "he must be stopped before x x x x" has been the rationale of every failed Neocon project of the past few decades. No more US blood and treasure must be thrown at endless wars that "mysteriously" benefit only the same cast of nefarious characters again and again and again.
When it comes to the Russia/Ukraine endless beef ask yourself a simple question: Why is nearly every anti-US, anti-West, anti-conservative, anti-Christian, anti-White, anti-Trump .org, NGO and individual, including the vast majority of Democrats and RINOs, the vast majority of leftists, the WEF, the UN, criminal grifters like the Biden Family and nearly the entire leftwing media and its rabid, nutbag "talking heads" division backing Ukraine? I'll bet a king's ransom that if Russia was still communist, the very same crowd - with a few exceptions - would be backing Russia instead.
At this point, whatever those scumbags are for, I am reflexively against because they never have my best interests in mind about anything.
“Why is nearly every anti-US, anti-West”
That fits Putin.
He promotes an end to the dollar, and an anti-US, anti-West coalition (BRICS+) to re-write the International order, to enable his wars of conquest and brutal oppression.
He wants an end to International rule of law, so his mafia orc world vision can run amok. His FSB (and KGB before that) has long directed efforts to attack the USA, stoking racial, class and gender divisions,; corrupting officials and sponsoring election interference. He is an enemy of America, who does what he can against us, until he can grow strong enough to do more.
