There is the matter of Executive Powers that you all seem to want to ignore here. The Constitution is clear on this, and it's been challenged numerous times throughout history. The President is obligated by the Constitution to fulfill his oath of office, and his power to do this in national security issues, always supersedes judicial or legislative orders, always has, and always must. If you take this authority from the elected president, you can give it to the legislative or judicial branch, or you can deny anyone this explicit power, either way, you cripple the government's ability to provide the one thing they are responsible foremost to provide, security for the citizenry. Decisions that must be made in a matter of seconds or minutes, would have to be presided over by judges or litigated by partisan politico's, and the opportunity to make effective decisions and take effective action, is lost.
