I would not expect many differences between the President-elect and Bush since they are closely associated with Israel. Emanuel's father for example, is a Jerusalem-born former member of the Irgun (Irgun Zeva'i Le'ummi), a military Nationalist group treated as a terrorist organization during British rule. His father emigrated to the United States from Israel and Emanuel volunteered as a civilian volunteer in the Israel Defense Forces during the 1991 Gulf War, serving in one of Israel's northern bases, rust-proofing brakes.
I could not imagine the President-elect differing much from Bush on the unqualified support for Israel which places Americans at greater risk.
