Open Source Code And War

"Should Open Source developers help the U.S. prepare for war with Iraq?" Roblimo has a piece on NewsForge which addresses that question by showing a specific way that the U.S. military is using Free and Open Source software (in simulator-based training for Blackhawk helicopters), and letting one of the developers involved speak for himself. If software is Free, doesn't that already answer the question of who can use it?
