After Russia invaded Ukraine 2 months ago it has become increasingly clear how horrendous the invasion is, with bombing of civilian targets, executions of civilians (including children), rapes, plunder, leveling entire cities to the ground, etc. The effects extend beyond Ukraine: Poland is overwhelmed with millions of refugees, and at some point Russia threatened use of nuclear weapons, which could lead to WWIII, although they backpedaled on that later.
It would seem that such evens are beyond partisanship. Whatever your beef is with your disagreeable neighbor, if you both see a murder being committed in front of your houses you both call 911 with the same message. And when the cops arrive, and you see the neighbor you hate telling the cop what you both saw, you don't start contradicting him just for spite, you don't say to the cop: "Year, I saw a shooting, but come on, why are you paying attention to this? Somebody trespassed on my property last week, and I've heard a pizza was stolen from a store down the street, why don't you investigate that instead? Also, my brother told me that the shooter is a good buddy of his."
However, as soon as Biden woke up and started to act (which took a while), several conservative talk show hosts and social media channels started minimizing the war. "Why are we sending aid to Ukraine rather than securing our own borders?" - this kind of BS. Tucker Carlson in particular.
And this point of view, which is almost "let Russian fascists take over Europe, it's not our business", is not consistent with the traditional Republican views on American role in the World and on US military. US under Bush-senior didn't hesitate facing Saddam when Saddam invaded Kuwait in 90s; add numerous other examples. Traditional Republican viewpoint: "you see evil - you confront evil." But not this time; to spite Biden's administration, or for some other reasons I don't understand, the current viewpoint seems to be "you see evil - you notice that your political opponent sees the evil, so you pretend not to see that evil is evil."
Why is that happening? Pure partisanship or something else?
