Shades of the Cold War...and Doctor Strangelove

America's entire Air Combat Command will stand down tomorrow. Investigators want to know why a B-52 was loaded and flown with nuclear missiles for the first time in 40 years. That story and Russia's aggressive new posture. Why has it tested a powerful new weapon and resumed Cold War-style bomber patrols? Also, a preview of President Bush's prime-time speech tonight and, on Reporter's Notebook, General Patraeus, Ambassador Crocker and President Bush say the alliance with Sunni leaders in Anbar Province is a sign of success in Iraq. Today, one of those leaders was killed.
