Seth Rogen and Michael Moore recently made snarky comments about American Sniper, Clint Eastwood’s Iraq War movie loosely based on the life of Chris Kyle, a Navy SEAL with 160 confirmed kills. This has angered a lot of people on the right, who scold the snarksters for their lack of appreciation for the men and women who, they say, defend our freedom. The “they defend our freedom” line gets thrown around a lot when discussing military policy, but when is it really the case that soldiers defend our freedom? Is this an automatic, intrinsic feature of being a soldier, or does it depend on additional factors? Let’s think about this.
