"The United States is committed to seeing this process through to a political transition away from Bashar al-Asad."

"Should the Syrian regime and Russian forces precipitate the failure of the COH, the United States will consider all available options."

"But I assure you that, because of the sectarian nature of this, if he thinks he is going to be better off fighting on behalf of a dictator..."

"the absence of diplomatic effort is almost a guarantee of failure."
