What is the logic behind this?
They feel threatened by China and not by Russia. Only one is perceived as real competition for the most powerful nation. Simple as that.
They recognize Russia is great power though, which is why strategically they think it’s really dumb and self-destructive to oppose Russia in a way that puts them completely aligned with China as we’re seeing with Ukraine war reaction from the US when Ukraine is not a strategically important country like say, Taiwan is. They see as misdirected warfare, not because of “we’re anti-war” narrative bullsh**t.
Republicans tend to be smarter and more cutthroat. They don’t care about morality behind stuff, more about their country interests as a priority.
