If we're going into perpetual warfare we need to bring back the draft. If the situation is that serious then there needs to be nationwide debate and bringing back the draft will probably bring this on. No deferments, no exclusions. Joe Blow's grandkids go.

Iran stood to one side when we took out Saddam Hussein. He was largely secular and if he was a practicing Muslim, he was probably a Sunni. Assad belongs to a branch of Shiite Islam. I doubt if Iran will stand by while we take out a coreligionist and possibly create another Sunni leaning state near Iran's borders.
