Sure, they would have, but personal motivations count for a lot of enthusiasm, and not just for Ukrainians, I've seen the attitude from the national security alumni on TV. It all adds up to a hostile foreign power who is attacking liberal democratic governments globally. I think the Biden doctrine is to support liberal democracies and help defend them from all kinds of attacks by Russia, like cyber, social media, or cybercrime, political assassinations and actual invasion. The fact that these guys are assholes helps in this task immensely as we saw after Bucha and other atrocities. The era of supporting strongmen who don't have any real domestic support is over, Modhi and Erdogan were elected, so was Orban.
