With both North Korea and Iran rushing to produce ICBM's that can deliver a nuclear warhead to cities in the US, it seems likely that we will put more emphasis on developing more effective missile defense against strategic missiles, ICBM's. The success rate of the Ground-Based Midcourse Defense system stands at about 50%. Not to good if North Korea launched 10 ICBM's at 10 US cities and 5 hit their target.With the war in Afghanistan winding down the defense industry needs another threat to justify the massive military spending. Defense contractors are licking their chops hoping the fat little Korean blunders N korea into War.
