How Do Americans See Defense Spending?

Gallup:

Americans do not provide government leaders with clear-cut direction on making defense cuts. They currently tilt toward the view that there is too much spending on defense, and that figure has increased slightly, from 31% to 39%, since 2009. However, almost as many Americans say current defense spending is about right, and combined with the 22% saying it is too little, the majority of Americans would theoretically oppose defense cuts.

Ezra Klein isn't so sure about that last sentence.
