As sectarian fighting in Iraq spreads, there's a Facebook meme that captures the public's frustration with the relative costs and benefits of America's military intervention in that country. The image makes a simple claim.

"For the cost of the Iraq War we could've ended world hunger for 30 years," it says.

Lee Camp, a stand-up comedian and host of the RT show Redacted Tonight, posted it on his Facebook page. Camp said he didn't come up with the message, but it made sense to him.
