A National Missile Defense (NMD) system has been the topic of much debate in the United States for more than half a century. According to its supporters, such a system would provide a sort of protective shield against a limited missile attack. In 1999, the U.S. Congress decided that the time for talk was over -- they passed a bill calling for the implementation of the NMD system to defend the United States from a growing number of countries developing long-range missile technologies.

The United States has plans to deploy a national missile shield within the next decade.
During the 2000 presidential campaign, George W. Bush made it clear that his administration will strongly back a NMD program, even at the expense of damaging U.S.-Russian relations. Russia has protested the U.S. government's plans for a national missile shield. Since taking office, Bush and Secretary of Defense Donald Rumsfeld have pushed ahead with plans to build the $30.2-billion missile-defense system, and might have it operational as soon as 2005.
