All you need now is to help the people of North Korea and give them freedom. They do have weapons of mass destruction, they are communist, the do have public executions as well as mass executions. The do violate human rights as well as holding 100000s in camps/prisons as political prisoners. Why not do them? Because its pointless for US. It will cost a lot of money, a lot of people will die and they dont have any oil. I will probably get flooded with red now...
he he By the way, its not just US. I just picked an example. Any war is beneficial to someone. A country would not go to war for their believes if there is a chance of their economy going pear shaped as a result.
