The War Powers Act of
1973
http://www.cs.indiana.edu/statecraft/warpow.html""Sec. 3 ...The President in every possible instance shall consult with Congress before introducing United States Armed Forces into hostilities or into situation where imminent involvement in hostilities is clearly indicated by the circumstances, and after every such introduction shall consult regularly with the Congress until United States Armed Forces are no longer engaged in hostilities or have been removed from such situations.""
Clearly indicated by TRUTHFUL circumstances, since lying to Congress is supposedly a punishable offense, except when Republicans do it of course.
""Sec 4 ...Whenever United States Armed Forces are introduced into hostilities or into any situation described in subsection (a) of this section, the President shall, so long as such armed forces continue to be engaged in such hostilities or situation, report to the Congress periodically on the status of such hostilities or situation as well as on the scope and duration of such hostilities or situation, but in no event shall he report to the Congress less often than once every six months""
Clearly, endless war was not envisioned when 'scope and duration' are mentioned above. The War Powers Act of 1973 is embedded within the Joint Resolution authorizing the Iraq war. It is time for Congress to pull US troops out of Iraq or else explain to the people why the War Powers Act is being abused.
