What's behind the new Arab momentum?

As expected, Vice President Dick Cheney's mission to the Middle East has been drawn into the Israeli-Palestinian conflict. The Bush administration appears to have seen this coming and has reacted with speed and skill. President Bush rebuked Israel on Wednesday for its invasion of Palestinian territory. The administration also authored a Security Council resolution, which passed, calling for a cease-fire and 'affirming a vision of a region where two states, Israel and Palestine, live side by side.' The State Department called for a 'complete withdrawal' of Israeli forces from Palestinian areas, and the president's envoy, Gen. Anthony Zinni, arrived last night to help broker a cease-fire.
