Russian is not going to be weakened. Their strategy is to bleed Ukraine at what ever cost including bleeding themselves dry. It is a war of attrition. Our fedgov prolongs this war to launder money through Ukraine. That is their only objective. They don’t give a crap about the Ukrainians or their country. It’s all about the Benjamins.
At this point, the US government seems to be spending a lot of money to get as many Ukrainians killed as possible. I don’t see Russia “losing”. I see a great many Ukrainians dying. And people seem pleased to cheer it on.
