We already are just by sending them any aid what so ever. Putin is nuts and needs to be put down. We need to not only enforce a no fly zone but put boots on the ground and push he and his all the way back to Moscow and then take the whole country once and for all. The season is now ripe for it with summer on its way. We then need to start taking out every other autocrat on the planet. They are an existential threat to everything and everyone now. There can be no peace as long as they continue to oppress their own people and threaten borders around the world with their psychotic ambitions.
