The question that kept many a Cold Warrior awake at night was usually one of how to keep anyone in the chain of missile launch command from starting a nuclear war without considering the consequences, if they weren't 100 percent sure of a Soviet first strike, or worse, just firing nukes off on a whim? But someone wondered – what if someone had to die to be able to launch the U.S. arsenal?

Do we get to choose who? Because I have some ideas.

Like the old urban legend of Special Forces operators being forced to murder a dog, or their dog, or whatever animal the urban legend mentioned, imagine how the thought process of launching a nuclear attack on the Soviet Union might have changed if one of the key holders had to die for the United States to be able to launch its missiles. This was the thought experiment posed by Harvard law professor Roger Fisher. Fisher wanted to consider the idea of surgically implanting the launch codes in a human body.

Right now, the President is followed around by a military officer who holds the "football," a suitcase that contains all the codes needed to fire off a nuclear weapon – or all the nuclear weapons. But what if the President of the United States had to kill the man who held the football to be able to extract the codes? Would it be so easy to launch?

Imagine how pissed Reagan would have been to find out the code was "00000000."

Fisher's rationale was that a President being briefed by Pentagon officials would have to talk through what was about to happen in a very matter-of-fact, unemotional way. He would be repeating lines of codes, ordering unspeakable horror in the blandest way possible. Fisher thought the President should have to make an emotional stand in order to fully execute and understand what he was about to do – to ensure that it was absolutely necessary, he should kill the first casualty himself.

The codes would be in a capsule near the heart of the volunteer holding the football, and now the football included a large, sharp knife for the President to use. This way, there would be no chance the volunteer would survive the interaction with the President, and the President would see the results of what he was about to do. In Fisher's words, "Blood on the White House carpet. It's reality brought home."
