This research paper argues that or the first time in many years the United States must re-consider its homeland defense policies. Technological advances coupled with rapid globalization provide potential enemies a myriad of capabilities to either directly attack the United States homeland or to use the threat of attack to shape its policies. Among the capabilities potential enemies may use are terrorism, ballistic missiles, cruise missiles, WMD, and cyber attacks. The United States currently has or is in the process of developing numerous policies and programs in an effort to counter these threats yet the end result is that currently the United States has no overarching policy to ensure the protection of its homeland and its citizens. Failure to develop a coherent, synchronized homeland defense policy will result, at best in the wasting of billions of dollars, and at worst in the loss of many lives. This paper looks at the potential threats to the homeland of the United States; reviews current laws and polices designed to counter these threats; and examines the role the armed forces play in executing these policies. This analysis is followed by a discussion on what is needed to develop a viable homeland defense policy and the role the military should play in that policy.
