Since war isn't exactly something planned like a special graduation reunion, the president might not always have enough time to fly to a fixed command center in order to sit around in dimly lit rooms full of handsome, brilliant scientists and psychopathic military advisers.

Now, the president can launch our nuclear warheads on vacation in Hawaii.
