The Nuclear Age
In 1945, a single bomb flattened a city and split history in two. The logic that followed — mutually assured destruction, arms races, nonproliferation treaties, the terrifying calculus of deterrence — has governed great power relations ever since. This track starts with why rational states threaten suicide, moves through how weapons spread despite every effort to stop them, follows the Cold War standoff that defined the rules, and lands in the cases that are breaking them: North Korea's arsenal, Iran's program, and the great power competition that is eroding the arms control regime. The bomb hasn't been used since Nagasaki. Understanding why is the most important question in international security.
The terrifying part isn’t the bomb. It’s that the entire framework preventing its use is a set of gentleman’s agreements between states that are no longer gentlemen — and the agreements are fraying faster than anyone is building replacements.
