They control the purse strings, they have all the power. Fortunately, the current leadership team seems to realize that a lot better than the previous one did and at least is trying to communicate with them, as opposed to the idiocy we witnessed under Skeletor v2.0 with the end around Eielson "draw-down" that was a BRAC in all but name that they didn't bother to talk to anyone in Congress about before trying to execute. But you aren't getting anything done without working with, not against, Congress.
Exhibit A for this: if you are talking seriously about a BRAC as being an option for cost savings anytime in the next decade, you don't have a clue. Congress will not be authorizing another BRAC anytime soon.
