If that President compromises the security of
the Federation, there will
be Powers That Be, elected or appointed, who could and would
sanction it. Again, your lack of 'gray' vision blinds you to reality; accept it - reality is not
black and white. That's not even just fiction - it's fantasy
. You may not like
that, and that's perfectly fine, but the gray not only exists, it vastly outweighs the black and white, and is ultimately what turns the wheels.
