"So - my question is: how can the Jewish Israelis maintain their own security in a way that does not oppress non-Jews?"

I don't want to be giving glib or clever-clogs answers, Joe, but the best way of achieving that security would be to stop oppressing non-Jews in Israel, to unblock Gaza and to jaw-jaw first with the neighbouring states before going into attack mode. There's an awful lot of unresolved chicken-and-egg about conflicts in that region. Jim may not like that, but I don't see too many innocents in the mix. Israel has the prosperity, the allies and the influence to make far more positive moves than it has done towards solutions. And those allies could be a damn sight more critical whilst still remaining allies. That lack of REAL criticism, along with the lack of conditionality in their dealings with Israel, is a massive part of the problem. It simply feeds the hubris of the regime.
