Barbour: Iran biggest threat to global security

HERZLIYA, Israel — Mississippi Gov. Haley Barbour says Iran is the world’s top threat to peace and stability.

Barbour, who is a potential 2012 presidential Republican candidate, says world leaders should be judged by their success in responding to Iran’s nuclear program and what he says is its support for terrorism and destabilizing governments abroad.

The popular governor received a warm ovation from a prestigious security conference Wednesday in Israel – where Iran and its nuclear program are a major concern.
