I probably could have convienced he BoS to ally with House, and they'd probably
Jump right on it, considering all he pre war tech hes got.
But the ignorant [censored] wanted them blown up.
That's when I gave him the gift of a golf club to the brain.
I don't think you quite know who the Brotherhood is. If you've only played Fallout 3, you might think the BoS are all white knights, which is simply not true. The Brotherhood in California is notorius for taking tech for themselves to 'prevent another apocalypse' yet bizarrely enough they use this very same tech to wreak destruction on those they deem it's enemies. The Brotherhood would NEVER ally with House because simply put, he has better technology than the Brotherhood that they could only DREAM of owning. The Brotherhood DOESNT share, they never have. Perhaps during Fallout if you do a certian ending, but in general, the Brotherhood likes to use weapons technology on others, while never saving Pre-War autodocs, prosthetics, and other helpful to humanity technology, they only gather and preserve the weapons technology.
