Threat Assessment BriefMarch 8, 2013
Ten years ago today, President George W. Bush said in a radio address to the nation: "It is clear that Saddam Hussein is still violating the demands of the United Nations by refusing to disarm." Eleven days later, he announced the invasion of Iraq to remove the weapons of mass destruction (WMD) allegedly possessed by Hussein's brutal regime and to prevent their use by or transfer to terrorist networks such as al Qaeda.

Threat Assessment BriefJanuary 30, 2013
Although plans for expanding U.S. strategic missile defenses focus on the Iranian ICBM threat, that threat is not emerging as was previously predicted. Iran conducted no long-range ballistic missile tests in 2012 and has not flown even the larger space launch vehicle that it displayed two years ago, which could have helped advance ICBM technology. Moreover, Tehran has still not decided to build nuclear weapons and continues to focus on short- and medium-range rather than longer-range ballistic missiles.
