Yes you do. If you support the U.S. taking our money and giving it to Israel without our consent then you also support the same for the Palestinian Authority. You're just happy we happen to give more to Israel then Palestine. But the reality is you have no real choice. If the situation were reversed you would squeal like a stuck pig about it.
It's all wrong because it's theft. If you won't agree to that then you support aid to Palestine, Afghanistan, the KLA in Kosovo and ISI in Pakistan.
