Commissioned officers do not make political decisions in this country, unless I woke up this morning in Guate-f***ing-mala and some O-6 just stormed 1600 Pennsyvania to proclaim himself "President for Life."
You are way out of your depth. Political decisions are about the only kinds of decisions that JCS makes.
You are the one who would undermine the Constitution by denying Congress its oversight role, not me. You are the one who suggests that constitutional officers stiff arm the Congress while leaving the military to operate on its own, unsupervised, not me. That the president is the commander in chief does not mean that decisions that commanders make are not political decisions, i.e. issues of policy that are ultimately subject to ratification by the voters through their elected officials. War is the continuation of politics thorugh other means and the actions of commanders must be understood in that light.
