The recent 15th anniversary of the September 11, 2001, terrorist attacks on the World Trade towers was a reminder of the terrible consequences when a nation ignores the lessons of history—including its own recent history. The U.S. military budget is a tragic example.
We currently spend roughly $598 billion on defense, which is more than the next seven biggest military spenders combined: China, Saudi Arabia, Russia, the United Kingdom, India, France, and Japan. This represents 54 percent of federal discretionary spending. In return, we get an ability to rapidly deploy conventional military power anywhere in the world.
