Speaking to the Huffington Post on September 5, Kerry said:

Constitutionally, every president, Republican and Democrat alike, has always reserved to the presidency, to the commander-in-chief of the armed forces, the right to make a decision with respect to American security. Bill Clinton went to Kosovo over the objections of many people and saved lives and managed to make peace because he did something that was critical at that time. Many presidents have done that… A lot of presidents have made a decision that they have to protect the nation.
