people, when that IS necessary. The hideous problems that arise out of that Presidential responsibility are rooted in the corruption of our culture and political systems by corporations and corporate media that elect power abusers. So, though we also need the President and Congress to share these powers equally, blowback from a history of abuse of Presidential war powers in service to corporations is likely increasing our risks as we speak. This is one of the reasons that a mature, fully informed, politically active, and responsible Public is needed so much in order to vote the right kind of people/Presidents into office, so that s/he can manage the potentials for the authentic need of more unilateral action in a manner that reflects the will of the people better in whatever situation.
The state of the electorate and the corruption of our systems have given us, instead, a vicious and expanding circle in which past abuses increase the possibility of current and future abuses. Without whole new everything systems, I see no way to end these problems short of absolutely massive demand from the people. But I don't understand how, were that demand to effectively manifest itself, that power shared between Congress and the President can defend against any and all threats and I'm not willing to say that a disasterous error in this regard is worth the principle of shared war powers, especially when our reality is so vastly different from that in which that principle would actually be functional.
In short, we can't write perfect laws for everything, so it is necessary to free our people and do our best, so that we stand half of chance of getting the right kind of people into offices who will operate within the grey areas of laws and regulations as ethically and effectively as possible when necessary and then relinquish those kinds of powers as soon as possible.
