I think you need to check the Constitution. This is a representative government -- citizens only indirectly affect government by electing representatives. The President (thank God) is commander-in-chief of the military; the only way citizens affect the military, indirectly, is through their vote for the president.
The founding fathers, wisely, did not envision a government run directly by the populace, and although you may have faith in your ability to be the "ultimate check on everything in this nation" look around you -- you are but one of millions, many of whom don't even know how to spell "constitution."
Careful there,you are speaking to a expert on the Constitution!
