Opposing Israeli policies is completely legitimate.
Opposition to Israel's existence is almost exclusive to anti-Semites.

My answer had more to do with the ideological resons for supporting Israel and/or the war on terror.

I consider myself to be a "civilizationist" in terms of foreign policy. (This neologism, coined by myself and Lawrence Auster in deference to Samuel Huntington, has not quite caught on.)
I see a Clash of Civilizations as the defining issue of our age. We are in conflict with the Islamic world, China, and Russia. By conflict, I do not mean war. Rather we are competing and hostile, with occasional military flare ups. Our natural allies are mostly found among the descendants of Catholic Christendom and their colonies, in particular the majority-European British Commonwealth. Although it does not fit this mold as well as Australia, Israel is part of the West.

Of course, within the West, we have a serious conflict between nationalists, Trans-National Socialists (Tranzis), and Trans-national Corporatists.
