I'm not sure about many of the conspiracy theories.... but it is a fact that we're squandering so much of our resources on foreign war to enrich the lobbyists, to keep people divided, and to keep foreign lands in the state of perpetual war and instability.... which leads to things like terrorism and more sufferings. America does also have a role in training and funding terrorist groups, directly or indirectly... :/
We could be using all that resources to eliminate most forms of sufferings in America, to rebuild our entire infrastructures, and to ensure that everyone here can pursue any realistic dreams they have.... rather than the stagnation that we have now.
