Story Question

What Caused The Great War In Fallout

Short Answer

The Great War was caused by escalating global conflict, but Fallout strongly suggests powerful corporations like Vault-Tec benefited from the apocalypse and may have helped enable it.

Why The World Collapsed

Before the bombs fell, governments and corporations competed over energy, resources, and political control. Nuclear conflict eventually escalated beyond containment.

Why Vault Tec Remains Suspicious

The series repeatedly hints that Vault-Tec viewed nuclear war as an opportunity rather than a disaster. The company was fully prepared to continue operating after civilization collapsed.
