The US now
spends as much on "defence" as the rest of the world combined. You
don't spend that kind of money on defence.... not unless you expect
to take on the entire world. No, you spend the money because you are
an empire. And empires must throw their weight around; otherwise
they wouldn't be empires. Americans favour war because they think
war favours them. They have the best army on the planet; they can't
wait to use it.
