c’mon note,there will be major spoilers for Fallout’s first season below.

If you are yet to finish the series, this is your chance to head elsewhere.

Series creatorTim Cain had previously suggested it was China that started the war.

This is done through the eyes of Walton Goggins' pre-Ghoul character, Cooper Howard.

And, Barb answers: “By dropping the bomb ourselves.”

Cue jaws dropping (well, at least mine and Cooper’s).

“A nuclear event would be a tragedy, but also an opportunity,” Barb continues.

“This is our chance to make war obsolete.

Because, in our current societal configuration, which took shape without intentional guidance, we have friction.

We have conflict and we have war.

“And war, well… War never changes.”

Now, it isn’t directly revealed if Vault-Tec actually ever goes through with its plan.

We don’t see Barb or any Vault-Tec employees pushing a button marked “Apocalypse, go!”.

Are you surprised by this revelation?

Or, is this something you had suspected all along?
