Forgive my political naivety, but isn't allowing the President to act unilaterally when it comes to military action against any other country because there's too much risk of the plans being leaked if Congressional approval is sought solving the wrong problem? Might even be advantageous if military plans were leaked on all sides, since that would effectively create a military stalemate where no actual shooting or bombardment would happen because everyone knows and is prepared for it, thus rendering it pointless.
Or am I just being too liberal and wishy-washy in being amazed and disappointed that we can, collectively, put people on the Moon, eradicate some illnesses, treat others very well and improve life in many ways, yet we can't seem to find ways to solve many differences that don't involve blowing the crap out of large groups of people?
