As bad as this sounds it's best to keep limited assistance to Ukraine if it can be helped. How would it look like to an increasingly unhinged Putin, dictator with a nuclear capable ICBM system, when the army of a country they invaded are rolling down the road to Moscow with highly advanced American equipment? There are two positive ways to end the war:
-
Ukraine invades Moscow with limited western support giving him less of a justification to send retaliatory missile strikes all over the world.
-
Things look so bleak even to the most financially comfortable Russian citizen that his own people turn on him and manage a successful coup before he can escalate things any further.
There's a great Behind the Bastards coverage of him. It's amazing he suffered under the Nazis as a kid only to become a sympathizer for fascists later.
