The most brutal Palestinian terrorists were Zionist Jews and not Palestinian Arabs.
The bombing of the King David Hotel was as shocking to contemporaries in 1946 as the destruction of the World Trade Center in 2001. British prime minister Clement Attlee declared in the House of Commons, ‘On July 22nd, one of the most dastardly and cowardly crimes in recorded history took place’. The bombing of the king David hotel was the culmination of Jewish Zionist terror campaign that was launched in the 1940's and targeted British and Palestinians alike. The "Ezel", "Lehi" and "Irgun" were Zionist terror groups that kidnapped, executed and murdered British soldiers. Using home made bombs and random shooting, they also indiscriminately murdered Palestinian men, women and children.
Two futures Israeli prime ministers, Yitzhak Shamir and Menachem Begin, were among the perpetuators of that indiscriminate massacre at the king David hotel in 1946. Just as Osama bin Laden is a hero for fundamentalist Islamists today, Begin and Shamir were seen by many Jews in Palestine and in the Jewish Diaspora as a fearless freedom fighters combating an alien tyranny. But unlike Osama Bin Laden and other terrorists who faced justice for thier horrible crimes against innocent people, Yitzhak Shamir and Menachem Begin went on to become the head of one of the most powerful states in the middle east, Israel.

Basically what Palestinian gorups are doing today, as in using terror to achieve its aims, is not that different from what Zionists terrorists did in Palestine in the 1940's. The Zionist terrorists were so successful in their ruthless terror campaigns, that they ultimately drove the British out of Palestine, which enabled the Zionist movement to conquer it in 1948, and created the state of Israel. In fact Israel's former head of the army, defence minister and prime minister, Ehud Barak, had stated that "If I were a Palestinian at the right age, I would have joined one of the terrorist organizations at a certain stage."
