In a sense, war is mostly logistics. It doesn't matter how strong your unit is, how clever you tactics are, or brilliant your strategy is. None of those things matter if the unit is not where they need to be, with the supplies to be effective.
Most countries have limited ability to project military force outside their country because the logistics become so hard to support. Russian military relies heavily on rail transport, which doesn't extend into Ukraine anymore, and trucks what it can't rail...but the supply depots need to be hundreds of km behind the line because of long range precision missile strikes. With long supply chains supported to heavily stretched trucking, guys at the front won't get everything they want.
Supporting Ukraine IS anti-war.
It's a war of aggression and the fastest and ONLY way to stop such a war is to stop the aggressor. Appeasement simply allows the aggressor to continue perpetuating or expanding their war aims.
The waste is trickling arms to them instead of surging it. We need decisive Ukrainian victory to spare the lives of Ukrainians and Russians from Putin's war.
