You are correct, Putin is much more like Mussolini rather than Hitler.
Also
Ukraine 2022 = Greece 1940
But the difference is Mussolini didn’t have 6,000+ nuclear weapons which is why we need to be very cautious.
Give Ukraine defensive weapons and push hard as possible for a negotiated settlement/end of the war.
It is the only sane policy.
Mussolini used poisoned gas in Ethiopia.
