The whole cluster bomb thing sounds like desperation. Ukes are losing big. Will they drop them on Russia Proper? You bet—in a week of getting them-in hopes Russia will become angry and do something to get NATO/USA involved in the war. Ukraine, despite all the Baghdad Bob propaganda is losing and losing big. Politicians, even skilled ones, do not make good generals. The Spring/Summer? Fall offensive is all a political move and will cost Ukraine its new shiny tanks and trained armies, all to gain a few miles of territory for Propaganda. Unlike the past wars—this one is a different animal. Ukraine must have USA Troops or they are lost. Putin can just wait them out for as many years as it will take.
You are in favor of direct US military intervention in Ukraine?
It is a European war, let Europe fight it.
Increasingly Europe understands the threat of Russia.
