As President Obama prepares to travel to Indonesia, his administration is seeking to reverse a 12-year-old ban on training an elite unit of the Indonesian military whose members have been convicted of beatings, kidnappings and other abuses. The administration is floating a plan to test a training program for younger members of the Indonesian Komando Pasukan Khusus, or Kopassus. Four members of the force, including its commanding general, Maj. Gen. Lodewijk Paulus, are in Washington to discuss the proposal, several sources said.
