I would say that all the western support for Ukraine has been designed to prevent Ukraine from losing, and so far it's been insufficient to assist Ukraine in winning.
The Ukrainian people and the Ukrainian military have done a tremendous job in attriting Russian conventional capabilities.
At the same time, the Russians are recapitalizing those capabilities from their factories, with their people, in order to pursue a wider war. We need to provide Ukraine with the weapons she needs to defeat Russia.
Putin's Russia needs to lose. In every case historically, when the Russians have lost—even, often, when they have won a war—it has led to fundamental political and domestic social change. Sadly, in the past, those changes were not always positive and didn't turn out well, but I remain optimistic. My first foreign posting was in Russia. I like the Russian people, but I cannot stand their government.
