American foreign policy is horrendous 'cause not only will America come to your country and kill all your people, but what’s worse, I think, is that they’ll come back 20 years later and make a movie about how killing your people made their soldiers feel sad.

Over scarce resources - yes that is a plausible scenario indeed. That’s why a plan is essential in order for people to be able to believe in such an undertaking. The groups will need to federate on the level of neighborhoods, towns, cities, states, nationals, and eventually, the planet. If attained, that’s all the protection they’ll need. But granted, that’s a big if.
