What Bush did call for, in his speech, to be done immediately: "The world expects an immediate cease-fire, immediate resumption of security cooperation with Israel against terrorism and an immediate order to crack down on terrorist networks. I expect better leadership, and I expect results....And so I've decided to send Secretary of State [Colin] Powell to the region next week, to seek broad international support for the vision I've outlayed today. As a step in this process, he will work to implement United Nations Resolution 1402 -- an immediate and meaningful cease-fire, an end to terror and violence and incitement; withdrawal of Israel troops from Palestinian cities, including Ramallah; implementation of the already-agreed-upon Tenet and Mitchell plans, which will lead to a political settlement." "
