George Birnbaum, an international political consultant who once served as chief of staff to Israeli Prime Minister Benjamin Netanyahu, is warning that a domino-style collapse of moderate Arab regimes could lead Israel to war.Birnbaum, an expert in global politics, cited Friday’s collapse of HosniMubarak in Egypt and the growing turmoil in nearby Jordan as ominous signs for Israel.Israel’s neighbor on the other side of the West Bank is ruled by King Abdullah II, a constitutional monarch who is Hashemite, a minority. Abdullah reigns over a population that is 70 percent Palestinian.“He had to relieve his government a few weeks ago,” Birnbaum told host Stuart Varney of Fox News on Friday. “If that country goes, and in Bahrain and other countries, suddenly you’re going to find Israel in a similar position it was in 1948, where it’ll be isolated, surrounded by Islamic countries looking to see its destruction — with the one exception that Israel has the ability to defend itself this time.“But that creates another problem,” he added, “which is a regional if not greater war that the world will have to face.”Birnbaum said Israel could be “in great danger.”
