“Nobody has advocated we go to war with Russia. We have been advocating that we send weapons and material support to a sovereign country being invaded by Russia which is being led by a truly delusional mad man.”
...and then what. Do you REALLY think that will make a difference there, other than result in millions of deaths, rather than thousands. If Putin is as delusional as you say, he WILL take Ukraine, and given its proximity to Russia, it will take a bit more than some RPGs to stop him. In fact, it will take WW3, if he is as delusional as you say.
So, other than making Ukraine go through another genocide like they did in the 30s, what’s the point of arming them - when they’re going to be defeated anyway?
I expect Putin will probably be sending Ukrainians to Siberia if he wins.
