I think each country has to decide for themselves what they’re going to do about the Russian invasion of Ukraine. Especially those countries who have been on the receiving end of US unilateralism as described in the article.
Despite all the past offenses of the US and the west, in this instance I think the west is acting as a force for good. Ukraine was invaded by Russia under false pretenses of “denazification” . The Ukrainians are asking for help to resist an invader. We should help them.
