What should the consequences be?

Syria violated the terms of the CWC. A treaty that they agreed to with nearly the entire world. Should we send them a letter and ask them pretty please don't use wmds on innocent children again? Should we do nothing like the spineless coward Obama did? They did a terrible thing. Little babies choked on their own mucous and vomit slowly and died a terribly painful, slow death. Are we, as the leader of the Free world to sit and watch and do nothing when Syria was in clear violation of an agreement they signed and ratified? frick that. USA did the right thing
