:

Prior to World War II and the RAINBOW series of War Plans, the U.S. maintained several color-coded war plans in case hostilities broke out with different countries. The US still maintains various war plans for Korea, Iran, and other contingencies, but we thought to modernize the different war plans for the present day, not including the Cold War.

(Note: The author has no knowledge of current war plans of the United States, beyond which can be gleaned from internet sites such as www.Globalsecurity.org)
