It is in fact your framing of the issue is dishonest, because you can't prove that lack of support for Israel has kept any country safe, or that it will keep ours safe.
Maybe you should go back and read what OBL said about the reasons for carrying out 9/11? Or would that be "giving in to terrorists" since they hate us for our short skirts and presidential elections, and not because of our interventions in their world?
But like I said, you seem to think that terrorists killing Americans and pointing to the US Government's 100% unflinching support of Israel as justification is worth it because it makes us "tough", and not committing generations of Americans to fight other peoples' religious wars is "cowardly".
