While I loathe the use of force, ISIS isn't a "traditional" enemy; therefore, POTUS, as Commander-In-Chief needs the ability to quickly respond to actionable intelligence. That said, there should be STRONG oversight by Congress with clear limitations on the rules of engagement: At no time, whatsoever, should the president or any regional commanders be allowed to knowingly violate ANY Articles of The Geneva Convention (hereafter, "The Articles"). Furthermore, if any military action violate The Articles, AND, prior to said action, any Officer in the Chain-of-Command held the reasonable belief that such military action held a high probability of violating The Articles, such Officer(s) shall communicate their objection up the Chain-of-Command, and, without penalty, legally refuse to execute any orders which stand in opposition to The Articles; furthermore the objecting Officer(s) shall be called to testify before Congress forthwith; further, should POTUS, SECDEF or any Officer in the Chain-of-Command override or circumvent the subordinate Officer(s) whose objections were properly voiced, AND a violation of The Articles occurs, the Officer(s) who knowingly disregarded the objections of subordinate Officer(s) shall be tried for War Crimes in a manner prescribed by either the UCMJ or The Congress; furthermore, after appropriate discovery, The House of Representatives SHALL, according to The Constitution, consider a Motion to Impeach The President and/or any other Member of the Executive Branch whose appointment falls under The Senate's "advise and consent" role. If convicted in The Senate, The Congress shall determine whether to surrender the convicted to an International Tribunal or other High Court of Competent Jurisdiction for trial as prescribed in The Articles, or, alternatively, to create and instruct a Special Prosecutor to try the convicted in the United States Supreme Court or in another U.S. Court deemed appropriate by The Congress; however, should The President and/or The Vice-President be Impeached and convicted as prescribed by The Constitution, The Congress shall prohibit the extradition and trial of the ex-president or the ex-vice president on foreign soil, but shall create, appoint and instruct a Special Prosecutor to try them only in a US Court of Competent Jurisdiction. In all other cases, The Congress shall have the sole power to determine the Court or Tribunal of Primary Jurisdiction.
