"All that is necessary for the forces of evil to triumph is for enough good men to do nothing."
Regardless of an agenda of the US, or your feelings concerning the US, there is no doubt in my mind that the government of Syria has and is currently perpetrating atrocities against its own people in the form of rape, pillaging, torture, murder, etc. It is a sad day indeed when the direction that lines run on a map are used to justify that it's okay to allow a government to systematically kill innocent men, women, and children.
The brutalization of innocent people should be everyone's business.
