An administration with a foreign policy team as chaotic as ours is right now isn't ready for what's coming. GAZA (Reuters) - A Hamas rocket killed three Israelis north of the Gaza Strip on Thursday, drawing first blood from Israel as the Palestinian death toll rose to 13 and the military showdown lurched closer to all-out war. Israeli warplanes bombed targets in and around Gaza city, where tall buildings trembled and thick plumes of smoke and dust furled into the sky. The Palestinian Islamist group claimed it had fired a one-tonne, Iranian-made Fajr 5 rocket at Tel Aviv in what would be a major escalation. But there was no reported impact in the Israeli metropolis 50 km (30 miles) north of the enclave. Israel's sworn enemy Iran, which supports and arms Hamas, condemned the offensive begun by the Israel Defense Forces (IDF) as "organized terrorism". Israel was more concerned about the mood in Egypt, whose new Islamist government brokered a truce between the two sides on Tuesday only to see it shattered a day later when Israel assassinated the top Hamas military commander. Hamas is an offshoot of the Muslim Brotherhood which now controls Egypt, Israel's most powerful Arab neighbor and a crucial partner in the 1979 peace treaty that stands between fragile stability and regional chaos. Cairo condemned the offensive and recalled its ambassador to Israel. Israel's ambassador left Cairo on what was called a routine home visit and Israel said its embassy would stay open. DAY TWO Israel's Iron Dome interceptor system shot down dozens of some 130 rockets fired from Gaza in the first few hours of daylight on day two of Operation Pillars of Defense, the army said. But one of those that got through caught its victims before they could reach the blast shelters that are everywhere in the Negev region, prey to sporadic Palestinian rocket attacks from Gaza for the past five years.
