Now I'm not going to shed a tear for Putin if he has to flee Moscow and we find him in a hole in the desert with a long beard, but the US track record for _successful_ regime change isn't exactly stellar. The middle east is still a mess, Korea is still divided, Vietnam was a colossal failure, and there are more examples in Latin/Central America than I care to cite.
IMO "Equipment" is a very tame and benign term for the deadly munitions we're supplying being used directly against an hostile nuclear power. It's not like we're only sending medical supplies and other errands of mercy. It just seem very risky to me to assume that the Putin is forever just going to ignore the fact that his soldiers are getting blow up by American weapons.
Russia has been doing what they can regarding foreign equipment to Ukraine.
It’s not much because all they can do is not much.
Short of ending his country by attacking NATO there’s not much more they can do.
IMO that assumes that Putin is a rational actor. I'm not sure that's the case.
