"Despite the breadth of the modern conscientious objector regulations, they continue to limit the availability of the exemption to those who selectively object to participation in particular wars. According to the Department of Defense, “An individual who desires to choose the war in which he or she will participate is not a Conscientious Objector under the law. The individual’s objection must be to all wars rather than a specific war.” To date, the Supreme Court has always treated conscientious objector provisions in the military context as matters of legislative grace rather than constitutional entitlement."
