Okay, so we feed and educate some other nations people, so that nation can now afford to put 45% of it's GDP into weapons and military. I don't think that will accomplish what we want it to accomplish.
I agree with you, but do you think if we send a bunch of food to one of these despotic nations the people there would actually get fed? If you really want to feed and educate the world, you also have to police the world.
I'm not saying the US currently does either (feeds or polices the world), but just pointing out that spending the military budget on food will not change much.
Despots are created and thrive on the backs of hungry and hopeless citizens.
