You are offered the position of Absolute Dictator of the United States for a period of 10 years. You can implement any changes to the Constitution, fire anyone, disband anything, change any law, even have people arrested and imprisoned or executed. True absolute dictatorial powers to remake the nation in the image you desire over the course of a decade.
But the catch is that you personally will be put to death at the end of the decade no matter what. It's the one thing you cannot change, cannot avoid, cannot alter in any way. Even if you do the best job ever, you will be put to death at the end of your term. So no clever 'I would change the rules so I don't' or 'I would flee to another country right before it's over' or other dodges like that. You absolutely will die after the term is over. You in essence will be performing a soldier's sacrifice, but only much more effective and individually focused. Instead of giving your life for your country in the hopes of saving it in the abstract, you personally will be able to actually save it in whatever form you think that takes, but you will absolutely be giving your life for it.
Do you take the deal?
I'm thinking there'd be a 1 year gap where people can form political parties & stuff, then have a general election :/ So making a (not literal) clone of yourself wouldn't work.
Now in my case, there aren't going to be many idiots left, so the Public can be trusted for a generation or two.
