A day that began with historic addresses to Congress by the leaders of Jordan and Israeli ended with joint condemnations of a terrorist bombing of Israel's London embassy. Israeli officials said the bombing, in which explosives in a parked car injured 15 people, was another sign of an all-out war by Islamic fundamentalists against the peace process. But the attack failed to overshadow the unprecedented appearances before Congress. Jordan's King Hussein and Israeli Prime Minister Yitzhak Rabin drew whoops and standing ovations from U.S. lawmakers by vowing to make their peace agreement work at home. The show doesn't come cheap. Jordan is seeking forgiveness of $1 billion it owes the U.S. -- something Congress must approve.
