President Obama has cast himself into the role of a vigilante. The use of chemical weapons is a world problem, as the president himself stated, not any single nation’s responsibility.
Punishing Assad is a moral undertaking. The invisible hand of the market may be good enough for economic problems. Moral issues, law and justice, need institutions, such as the World Court. The UN is the only available institution.
If authorized by Congress, that does not give Obama the authority to punish Assad on his own. Vigilantes deliver vengeance, not justice. Obama should take his authorization and relentlessly press the world as represented in the UN to fulfill the moral obligation it took regarding chemical weapons.
