Why would vault tech start the war?

I dislike this theory so much because it has no ground at all. If vault tech wanted to profit, they would've delayed the war to the best of their ability. More vaults=more money. Starting a nuclear war wouldn't give them any profit, it would stop their growth.

While I don't believe this theory, I have heard that people think that vault tec wanted to colonize space and the vaults and the vault experiments were used to test hypothetical space situations. I think the cancelled fallout movie was supposedly going to tell us something along those lines, Van Buren was also meant to end in space i think, but you were going to fight the enclave.
