"Judge Dredd" is set in a future Earth damaged by World War III, a nuclear war instigated by corrupt U.S. President "Bad" Bob Booth in 2070. The majority of the world was left an irradiated wasteland filled with hostile mutant lifeforms, with the surviving population being centralized in the so-called Mega-Cities, massive urban sprawls covering entire states created to deal with overpopulation during the 21st century. Further massive conflicts during the comics' present, such as the "Apocalypse War" against East-Meg (the government of the former Soviet territories) and the "Day Of Chaos" has caused even more destruction.
