The United States accounted for virtually all of the increase in world military spending in 2010.
And because the United States has the world’s largest economy, its share of world military spending is outsized, accounting for 43 percent of all the military spending on Earth — six times as much as China, which has the world’s second largest military budget and accounts for 7.3 percent of world military spending. Russia accounts for just 3.6 percent.
With polls showing declining support for the war in Afghanistan and increasing talk in Congress, even among Republicans, about cutting the military budget, it appears certain that the Defense Department is going to be downsized and our foreign military commitments scaled back in coming years.
This is going to require serious rethinking of what we perceive to be our strategic threats and whether the United States can continue to afford to be the world’s peacekeeper.
