It's all about Putin.
Of all the oppression, murder and genocide in the World they had to choose from they've always demanded the U.S. stay out of things. Don't be the World Police. Stop enriching the military-industrial complex. No more war for oil. Save the troops by not sending them to war. etc, etc.
But they've bought into the Russian collaboration hoax so deeply that they see Putin and Trump as one in the same. Kill Putin, and you kill the orange man. And they're more than happy to have Ukraine turned into rubble and NATO soldiers thrown into the meat grinder to get it done.
