@georgeob1,
I find myself wondering how much access people in McChrystal's position actually GET to the President?
Having been involved recently in a very serious and urgent situation (infinitestimal, of course, compared with a war!!!) where a bunch of Government Ministers (your equivalent I guess would be people in Cabinet) were involved, seemingly simply in order to destroy any chances of success by going against all the best possible advice coming from the people actually involved, I was struck by how little access even the topmost people in the organizations that came together to try and assist in the drama had to the people who made the decisions.
It was one of the most frustrating experiences I have ever had.
Does someone like McChrystal have direct access to Obama> Or is it all scrambled through a chain?
