How does the military make the world a better place?

I'm arguing with my brother and trying to come up with all the ways the military makes the world better.How does the military make the world a better place?The military provides security for a nation (thats the main one) also several million jobs in the uniformed personnel alone, don't even know how many who work on the base serving the soldiers as civilians. And wherever a military base is started, the surrounding community has a very stable economy as the servicemembers go off the base to Eat, Shop, Party. . . whatever. Very good for local economy.How does the military make the world a better place?Ask him if he likes having freedom.
