Why not answer to what I already said above: is a gun that's guaranteed to not harm you still a deterrent? Is a handgun a deterrent if you are in full-body heavy armor, in an armored vehicle, or just too far away? It's the same gun with the same bullets and the same power, nothing about it changed and lo and behold, the deterrent is gone just because it can no longer kill you.
That deterrent cannot exist without the threat, but the threat can exist without deterrent. A gun or a bomb which cannot kill you will not deter you. The object is worthless, the promise that it can harm or kill you is the only thing that matters. So the only point of the gun and the bomb is to kill. Everything else is a consequence that derives from that.
To answer your points:
Yes, the bombs were built with the single reason to be able to destroy cities and kill millions. Weapon specs don't list and quantify "deterrent" because that's not a characteristic of the weapon. If you build a guaranteed missile shield around you country then that exact "city killer" bomb is no longer a deterrent.
No, the authority is why police doesn't get punched in the face. The authority is backed mainly by law which gives them the right to fine or arrest. Taking away your money or freedom are the the real deterrents (as evidenced by judicial systems relying solely on this in most countries). In most of the world you can punch a police agent in the face and not get shot and people know that so they still do it.

You can lead a horse to water, and all that.
