Rather than leaving to Congress the issue of whether to declare war and thereby invoke various corresponding obligations, Plaintiff's would have this Court second-guess Congress's decision to authorize something short of "war." This is plainly not the judiciary's role. ... Congress is fully-equipped to analyze the treaties, policy considerations, and accompanying obligations that would follow from a declaration of war and to choose a separate path accordingly. The fact that the United States is engaged in military action absent a declaration of war does not automatically invite the judiciary's analysis as to whether that action is "constitutionally sanctioned."
