This map shows how enormous US military spending really is

Updated by Matthew Yglesias 

Not only does the US defense budget equal about half the world's total military spending, but a huge chunk of the rest of the total is spent by close American allies. Russia's military spending, for example, is dwarfed by the combined commitments of the UK, France, and Germany. North Korea's military spending looks like a tiny pimple sitting on the top of South Korea's head.
