Robert L Booth became Vice President in 2060, and rose to become the President of the United States in 2068. The election was rigged, he managed this by blackmailing the head of the company responsible for vote counting.
After being told by his advisers that their new missile defense screen could nullify any nuclear attack against the US, the insane President Booth decided that he had no problems going to war with the rest of the world if his long list of demands were not met.
Many of his cabinet, such as Arnold Benedict, Booth's Special Adviser held reservations about what Booth was planning. Benedict threatened to expose the rigged election to halt the move to war but President Booth had him murdered before he could do anything.
In 2070 Booth started the Great Atomic War, he had been told by his advisers that the US' missile defenses had advanced to the stage where they would offer complete protection, they had been mistaken. Most of the United States was turned into a radioactive wasteland, with only the most advanced missile screens over the East and West Coasts stopping 100% of the incoming nukes.
Later, in that year Booth was eventually deposed by the Judges (who were previously only involved in law enforcement, not the political running of the country), the Judges then set up a fascist regime, making President Booth the final President of the United States.
Booth was sentenced to 100 years in suspended animation, the Judges decided that they would leave his judgement to posterity, allowing their descendents, who were destined to grow up in this ruined US to decide his sentence for the crimes he had perpetrated against them.
President Booth was created by Pat Mills and Mike Mcmahon in 1978, first appearing in 2000AD #67
