What is Israel probably to do if Palestinians attack its soldiers during the pul

Israel is warning of harsh retaliation if it is attacked by Palestinians during the upcoming pullout from the Gaza Strip. In another development, the Israeli government expects half of the Gaza settlers will refuse to leave their homes voluntarily.
   Israel is planning to launch a massive ground operation if Palestinian militants fire on Israeli soldiers and settlers during the Gaza pullout, which is due to begin in mid August.
   "We would halt the evacuation of settlers for 10 days to two weeks and inflict a severe blow," said Israel’s Deputy Defense Minister Ze’ev Boim.  He said the army would send 12,000 to 15,000 troops to Palestinian towns near Jewish settlements in Gaza. The evacuation would resume once the army stops Palestinian fire.
   The Palestinian Authority has promised to ensure a peaceful Israeli withdrawal, but Israel doubts that Palestinian forces are willing or able to control powerful Islamic militant groups led by Hamas. But Palestinian chief negotiator Saeb Erekat says his side is ready.
   "We are determined to deliver, and to control, and to ensure that the disengagement’ will take place in a smooth and peaceful atmosphere," he said.
