Committing sociology isn't about thug-hugging; to say otherwise is simplistic. Strength and simplicity can occasionally prevail, but they can never be sustained. That's not winning - that's delaying defeat.
The only way to achieve victory is to destroy your opponent. Killing is but one way to do this - ultimately, a resource-wasteful one. They tend to fight back, doncha know. The best way to foster sustainable, conservationist wins is through conversion.
It's been true since the days of Sun-Tzu; it isn't going to change for as long as we're human.
