Who says the west is not getting into the fight in Ukraine? I think this is common to many wars and we all know of Hemingway volunteering for the civil war in Spain.\

The Russian army is not noted for their congeniality. There are already reports of them raping and killing Ukrainian women and girls. Any American mercenaries caught could expect little sympathy or could be used as propaganda for Putin and his generals. But for soldiers, adrenalin is the rush of combat, and Ukraine needs the help. I wish them the best and know there are volunteers from other countries going into the fight.
This is part of the uncontrolled response which makes events more catastrophic than they might have otherwise been. People with Big Brains.
