Daniel Pipes, the important scholar of Middle Eastern matters, had his speech on "The Threat to Israel's Existence" interrupted at University of California - Irvine by what he said appear to be " goons of an Islamist persuasion." His weblog links to videos of his speech (including the disturbances) plus there are links to several commentaries on the event. One of the videos includes Pipes' complete address which is a handy way to get up to speed on the current threat to Israel. (HT: Candace de Russy at Phi Beta Cons)
