No, it's not that simple. Argument by assertion. Putin does not represent any sort of imminent defense threat to the United States. We are not benefitting in tangible ways to funding the corrupt Ukraine. In fact, we are doing it to our detriment, which is one of the reasons so many lefties now like this kind of military interventionism. And, again, it's also connected to this simple math equation to them and to others: Putin = Trump and, therefore, the US + Ukraine > Putin/Trump.
We're playing with the prospect of nuclear war, which is always insanity. Zelenskyy's lying about the bombing in Poland a few weeks back demonstrates that the idiot is willing to provoke nuclear war. I have kids. I'm not amused or impressed by the virtue signaling and obligatory defenses that the next insane foreign policy to "stabilize" or "protect democracy" is paramount. Blow it out your derrieres.
