I agree. However, Israel cannot do anything which will reck the US roadmap to "peace."
If Bush tried to stop Israel, he'd lose the evangelical Christian vote (not to mention the Orthodox Jewish vote) and the election. He'd probably also turn off other conservative voters who are tired of the special treatment of the Palestinian terrorists. The press likes to pretend that all of those disgruntled with Bush's terrorist policies are on the left. But a big part of the unhappy are those on the right that think he's being too soft.
Sharon needs to call the administration's bluff and destroy the PA, Hamas and Hezbollah. Because that's what it is -- a big bluff by the US. The US is not going to war with Israel to protect Palestinian suicide bombers. And no other nation has the military capability to stop Israel. Clearly, France isn't going to get into a nuclear exchange with Israel nor is any of the other nuclear powers.
