Following the Tuesday airstrike in Syria, President Obama will face the United Nations General Assembly to defend his decision to bomb terror groups inside Syria without approval from the U.N. Security Council, Congress or an invitation from Syria.

Officials say that he will address the overall unease in the world given the new dangers posed by groups like ISIS and Khorasan, a senior administration.

Officials also add that more will be addressed by the president on the need to continue building the international coalition he and his administration have already begun to assemble.
