I mean, I understand that. I just think you underestimate how stupid and greedy these people are. Armies need equipment, training, maintenance, resources etc. All that requires money, money they don’t want to spend.
They’re real life min maxers. They’re trying to achieve the highest score with the least amount of effort and the least amount shared.
Plus, they’re stupidly arrogant. They think they’re geniuses at everything. Listen to someone who actually knows how to fight? For how much? Pfft they’ll do it themselves.
And then they’ll get overrun by a well organized and trained group.
