If you are aware of what they are doing, and you provide support to them, that is therefore knowingly providing support to their actions, whether you agree with those actions or not.

Or, if you just meant 'agree with' rather than 'supply', then I would say that what they're doing is not something they will ever stop. It's an integral part of their existence as an imperial Zionist state, they aren't just doing it for fun, or because of some 'bad apples'. They have no plan or desire to stop, their history is mostly just this same type of war and besieging repeated, and the USA would probably abandon them and let them collapse if they miraculously did decide to stop, because the US imperial strategy only values the Zionist Regime as a attack dog in the Middle East, a region critical for resource control.

A lot of words to say, it might as well be supporting guns without supporting bullets. There is no realistic situation where guns won't be used to shoot bullets. They can't be separated, in reality. Why support guns, at that point? It's just a comfortable abstract idea in a vacuum.
