To Tag I think? Anyways, it is kind of silly to think the BoS would wage war with a large army, properly equipped, commanded with competent leaders. I don't care how religiously fanatic a group can be, it doesn't mean their common sense just went to shit. The BoS simply do not have the numbers to just waste on a war that frankly has an impossible goal. The elders clearly saw some benefit with the hedge your bets as long as the probability of loss doesn't outweigh the gains. Declaring war with NCR is totally pointless when others pointed out that one of the possible endings shows the BoS actually assisting the NCR albeit not with the 'juiciest' tech. As far as I remembered, the BoS didn't mind folks getting access to tech like normal guns, grenades, etc. Even vault city had laser turrets and fences and they didn't go to war on them. What they didn't want was any force to get enough high technology to become a significant competitor/ hegemon. In regards to the NCR, they already KNEW that it was getting too big for their control so they wisely 'assist' with tech they don't worry as much about while using the assistance as a path to gain a controlling stake in NCR politics. Best example would be an almalgamation of the r&d ending in F1 and the BoS mission in New Vegas where they try their best to limit high tech since keeping it ALL out of heathen hands is an impossibility. Bethesda or all those other chuckleheads needed more enemy vvariety in their 'oblivion', with guns sotry and only wisened up with new vegas when f3 was clearly pointed out as stale and un-inspiring.
