Really?
The war in Ukraine is obviously the #1 most important, most critical issue for Putin right now. It is as close to do-or-die as a dictatorial nationstate can get and the situation is getting worse by the day for Russia.
If someone were to believe what you're saying is true then Putin would have invaded Ukraine under a Republican President, Trump. Russia only seems to fuck with Ukraine when a Democrat is President. Why would Putin invade Ukraine or fuck with Ukraine when the party in power hates Russia and will spend untold billions to stop Russia.
Your argument makes absolutely no sense.
Wait so... why would he? Considering this is exactly what he did?
Could it be that there are other components to a decision to invade than merely who is in power halfway around the world? There's nothing incompatible with this and the idea they he'd prefer Trump, or any NATO-withdrawing and foreign-aid withholding party, in power.
Why would Putin invade when a Democrat is president. It makes zero sense.
