Here's a reporting provision that is triggered anytime U.S. forces are deployed "into the territory, airspace or waters of a foreign nation, while equipped for combat, except for deployments which relate solely to supply, replacement, repair, or training of such forces." Here's the most discussed provision, which kicks in after a president reports to Congress that he has launched a military action:
Within sixty calendar days after a report is submitted or is required to be submitted pursuant to section 1543 (a)(1) of this title, whichever is earlier, the President shall terminate any use of United States Armed Forces with respect to which such report was submitted.
Another apparent violation -- but as noted, the White House vaguely claims that our actions in Libya are "distinct from the kind of 'hostilities' contemplated by the Resolution's 60 day termination provision."
Let's also visit the handy section titled "Interpretation of joint resolution":
Authority to introduce United States Armed Forces into hostilities or into situations wherein involvement in hostilities is clearly indicated by the circumstances shall not be inferred ... from any treaty heretofore or hereafter ratified unless such treaty is implemented by legislation specifically authorizing the introduction of United States Armed Forces into hostilities or into such situations and stating that it is intended to constitute specific statutory authorization within the meaning of this chapter.
It goes on to state:
For purposes of this chapter, the term "introduction of United States Armed Forces" includes the assignment of members of such armed forces to command, coordinate, participate in the movement of, or accompany the regular or irregular military forces of any foreign country or government when such military forces are engaged, or there exists an imminent threat that such forces will become engaged, in hostilities.
What's evident from all this is that President Obama's argument for why he is in compliance with the War Powers Resolution is mostly made up of irrelevant assertions. It doesn't matter that our Predator drone strikes are limited, or that we're mostly supporting the armed forces of other nations, or acting as part of an international body, or that the war was launched to prevent a humanitarian disaster. Nor does it matter that "U.S. operations do not involve sustained fighting or active exchanges of fire with hostile forces." None of those things gets Obama out of the requirements of this legislation, nor is there any hint in its language that they would -- in fact, insofar as it's specified, various provisions are triggered by merely being in another country's airspace or accompanying forces from other nations while they are engaged in hostilities.
The notion that we're engaged in a special kind of post-NATO-handover "hostilities" not covered by the War Powers Resolution is unsupported, and, even ignoring that, President Obama indisputably violated at least one other provision of the legislation before the NATO handover. Then there is the fact that President Obama has requested no funds to pay for this war.
