A good deal of those facts are taken out of context, misleading, exaggerated, or outright wrong.
However, I am a proponent that we need less a military presence in the world and more of an itelligence presence. More information, spies, drones, ect. would do more for us than military bases do, though these are often outposts for spies and intelligence community members.
Anyone who thinks we can turn a blind eye to the world, cut our military in half, and expect to live happily using the budget to feed the homeless is delusional. The world is an extremely delicate power balance, and there are a whole lot of factions that would build up their military as fast as we dismantled ours.
