The last people we gave heavy weapons to decided to burn down half of Iraq and declare a Caliphate.
If Putin invades Ukraine or part of it, he will suffer somewhat, but this is not worth nuclear war over, as much as John McCain might demand it.
Notice how nobody is talking about the diseased invasion of America by El Salvador?
Spare us the hyperbole. Russia will not nuke us for supplying arms to the Ukrainians, any more than we nuked them for supplying arms to Chile (under Salvador Allende), Cuba, Nicaragua, North Korea or North Vietnam.
If not now when? When they are invading Paris? Whether you believe in God or not, the fact is we have to stand for something, if Russia thinks it can boss it’s neighbors around we need to stand in it’s way. I realize as a 37 year old arm chair quarterback that is easy to say, I may not have to spill my own blood, however, given that I still believe that the right thing to do is pretend it’s the cold war all over again, we need to roll up a multitude of armor divisions up against Russian borders, we need the Air force to buzz the borders, we need to let the Russians know we will not tolerate this non-sense of invading neighbors. This includes at home against an unarmed invasion of immigrants. We need a leader that is capable of this and a country that can elect that leader. If not, instead of thousands or tens of thousands of causalities, we will be facing ten of millions, maybe even hundreds of million of dead people around the globe.
