Reluctantly, Israel re-entered the Gaza Strip only three years and four months

after leaving in August 2005. The withdrawal was unilateral, yet accompanied by guarantees; Egypt was to ensure the halt of all contraband smuggling into the Strip while the Americans obligated themselves to stand behind Israel in its battle against terrorism even should Israel need to cross into Palestinian areas. Rocket fire into Israel from Gaza began under Yasir Arafat's Fatah led Palestinian Authority rule already early in 2001, continued under Mahmoud Abbas (Abu Mazen) who was elected in January 2005 (Arafat died in Nov. 2004) and intensified when Hamas overthrew the PA regime in June 2007. Whether discussing a hudna (Islamic cease-fire) or tahdiya (Islamic period of calm) the shell fire continued from Gaza into the western Negev. The last tahadiya lasted half a year, from the middle of June to the middle of December and ended with a bang as Hamas began pounding Israel with 60 rockets a day. Despite the expectation of rain, cold and the least optimal conditions, Israel decided to respond with massive air strikes on Dec. 27 and began a ground offensive a week later.
