Rep. Barney Frank (D-Mass.) told The Huffington Post: "The liberal community's got to focus more on Afghanistan, Iraq, NATO. NATO is a great drain on our treasury and serves no strategic purpose." Lawrence J. Korb, a senior fellow at the Center for American Progress agrees: "We ought to rethink the whole idea of NATO."
Korb estimates that approximately 20 percent of the baseline defense budget is NATO-related, resulting in about $100 billion in spending each year. (Pinpointing the exact number is tricky, however, since many of the assets the United States provides NATO are used for other purposes.)
