The GOP has held onto the Nixonian belief that there needs to be some semblance of a functioning relationship between post Soviet Russia and the US to ensure global security. It was really odd to me that our latest national security strategy calls Russia an "acute" threat.
That worked when they were somewhat of an 'honest' actor, not so much nowadays.
Zelenskyy also isn't the great guy he's been made out to be after the conflict started.
While not without flaws he is a much better guy than the murderous thug across the border. Leaders ain't perfect and with his country's very existence is under threat he can have a little leeway, and compared to almost every other Ukrainian leader and many of his contemporary neighbors he has done a damn fine job.
