President Barack Obama appeared before the United Nations General Assembly Tuesday and stated that the United States will “do what we must” in order to stop Iran from gaining nuclear weapons. The President also used the event to commemorate the late Ambassador Christopher Stevens.

Stevens was killed along with three other Americans when the US consulate in Bengazi, Libya was attacked on 11 September. Obama stated that “there are no words that excuse the killing of innocent” people. Obama denounced violence in the Middle East and called for tolerance and democracy.

He stated “They are also an assault on the very ideals upon which the United Nations was founded — the notion that people can resolve their differences peacefully, that diplomacy can take the place of war, that in an interdependent world, all of us have a stake in working towards greater opportunity and security for our citizens.”
