From The American Spectator:
In supporting your country’s war efforts, it’s quite logical to invoke dastardly actions of the enemy. Historically those actions have been grossly exaggerated or fabricated. In this case, exaggeration is not only superfluous it’s essentially impossible. While taking their lunch breaks from blowing up civilians they do saw through necks with knives.
Actually, the overwhelming majority of terrorists do not saw people’s head off with knifes, and those that do probably don’t do it on their "lunch breaks from blowing up civilians". So any statement to that effect would be, you know, an exaggeration.
Apparently, the "impossibility" of exaggeration is itself somewhat exaggerated.
