April 19 marks the 15th anniversary of the bombing of a federal building in Oklahoma City - the worst single act of domestic terrorism in our nation's history and a grim reminder of the fruits of right-wing radicalism. The anniversary comes as the antigovernment militia movement is experiencing a resurgence.

Since the SPLC warned the U.S. military about extremist activity among active-duty personnel in 2006, the Pentagon brass has steadfastly denied that a problem existed. Recently, however, the military quietly strengthened its rules to prohibit a range of supremacist activities.
