"that same Constitution that gives us the order of succession also limits the power of the executive branch. That's something we keep forgetting, to our detriment." Dn
I hope it's a little more complicated than that.
We all know the textbook "co-equal 3 branch federal government" thing.
Even so:
the as yet unresolved "war powers" debate isn't going to prevent a genuinely genocidal madman from becoming U.S. commander in chief, and terminating the human race.
He's one of the few that can.
Be assured:
I understand the benefit of the unitary executive.
We don't captain our ocean liners with parliaments, that debate every decision before they vote on it.
If we did, half of them would already have run aground.
So we invest this supreme authority in one commander *, whose onboard authority is final, until the mutiny, or the judicial hearing.
* note:
The only exception I know is NASA's now retired shuttle fleet.
Those rocket ships actually were piloted by a parliament of 4 computers.
Landing them was fly by wire.
So the human would do the input.
Then the parliament would review the suggestion, vote on it, and any unanimous decision would be acted upon.
BUT !!
If there was a dissenting vote, that computer's voting privilege would be automatically, electronically revoked, and the remaining 3 would continue from there.
