They have done it in the past there is nothing stopping them doing it again. The worst case scenario is a nuke hitting down town. Israel know this and their existance is at stake.

Third Arab-Israeli War, was fought between June 5 and 10, 1967, by Israel and the neighboring states of Egypt (known at the time as the United Arab Republic), Jordan, and Syria. After a period of high tension between Israel and its neighbors, the war began on June 5 with Israel launching surprise air strikes against Arab forces. The outcome was a swift and decisive Israeli victory. Israel took effective control of the Gaza Strip and the Sinai Peninsula from Egypt, the West Bank and East Jerusalem from Jordan, and the Golan Heights from Syria. Opinions are divided on whether Israel's attack was an act of aggression or a preemptive strike of a defensive nature.
