Is it canon?

Because there's 1 small detail that really, really bugs me about it being canon.

There's 1 terminal in MotherShip Zeta that says, neither the U.S or China started the great war, but the Aliens did.

Something regarding the stealing of American launch codes and Chinese launch codes, it was either in one terminal in MotherShip Zeta, or it one the audio logs on the prisoners onboard MotherShip Zeta.

Had Bethesda said anything about it being canon?

I think the general consensus is that it is not considered Canon, but rather a giant Easter Egg with a lot of loot

All Bethesda developed games/DLC, and all officially licensed materials, such as New Vegas and its DLC, set in the Fallotut universe are canon, regardless of what people want them to be.

I don't consider it canon. To me it is the same as the Burned Game (Fallout Brotherhood of Steel) and it shouldn't be considered canon.

For now IMO it is in limbo, not canon and it isn't none canon because it hasn't been referenced in a future game and Bethesda hasn't commented on it.

Anyways I grow tired of these threads on Mothership Zeta and Aliens. Bethesda took a joke to damned far.
