harsh military retaliation; nevertheless, Prime Minister Ariel Sharon decided to not take any immediate retaliatory actions. U.S. and other governments applied heavy diplomatic pressure on Israel to refrain from action. Nevertheless, the attack was later on noted as one of the reasons cited by the Israeli government for building the Israeli West Bank barrier.
