It's probably in your back pocket again. :icecream:
I'm no NCR fan, but I can tell you why Moore is a bad leader for the NCR.
She was a Ranger, wounded during the BoS-NCR. Because of that wound, she got put behind a desk, something she seems to dislike. She holds grudges, she blames the Brotherhood for taking her out of the Rangers which is precisely why she doesn't want you to take the diplomatic approach. But who wouldn't want the Brotherhood-of-[censored]-steel on sides with them? The BoS helps at the Battle AND patrols highway 95, keeping it safe. All they ask in return is Salvaged PA Suits. She's not a stupid person, so it can't be ignorance that would make her refuse to have them help against the enemy, especially with an enemy such as The Legion. She lets her personal grudges get in the way of her work, and at her height of power that isn't good. There would definitely be an increase in causalities without the Brotherhood at the Hoover Dam.
Not just that, but her overall ignorance towards diplomatic approaches with The Great Khans and The Kings is disturbing too. The Great Khans are a powerful force, not something to be tossed aside at the hands of a Courier. They can also severely help at the Hoover Dam too, possibly decreasing trooper causalities. I just don't understand her, thinking that without any help the NCR can hold the Legion again. Even if they managed to do that, was it worth the huge amount of deaths that just took place? C'mon Moore. Maybe you're not cut out for the job afterall, maybe she does make a better Ranger.
