We prided ourselves in those same principles in World War II, and yet we were able to effectively manage it for OPSEC throughout that war.
Now the country does consider itself to be at war. There are no war bonds, victory gardens, rationing or paper drives. The military production lines take second place to consumer products. I fear this will be the norm until we have another wake up call, which will make 9-11 seem like a stroll in the park. Picture a nuke in LA or NYC or maybe Washington, D.C. The muslims have shown they have much more patience than the average US citizen has.
