If America and Israel did not use nuclear weapons when Russia(with Russian pilots) sent weapoons, and/or killed and attacked Americans(and NATO) and Israelis, then I expect Russia to behave the same way. Unless Russia is such a bully akin to Nazi Germany, then I see even more reason to continue the support to Ukraine and Eastern European countries.
I'm not sure how you can be so nonchalant about the possibility of needless nuclear war.
