In a high-profile policy address before the Council on Foreign Relations (CFR), Secretary of State Hillary Clinton declared that the US wouldn’t not hesitate to use its military to “defend our friends, our interests, and above all, our people” during the segment discussing Iran.

She elaborated on the declaration with “this is not an option we seek nor is it a threat; it is a promise.” Clinton also warned Iran that the US offer to hold talks, which she had previously said she didn’t expect to work to begin with, would not be open-ended and that “our willingness to talk is not a sign of weakness.”

Today’s comments are the latest in a long line of bellicose rhetoric coming from the Secretary of State. Last month during a television interview she said that Iran was risking the possibility of a US invasion, citing the disastrous 2003 invasion of Iraq as a model.

The US has been demanding that the Iranian government abandon its civilian nuclear energy generation program, and several officials have claimed, despite a stark lack of evidence, that Iran is working on nuclear weapons. The IAEA has pointed out no evidence for the accusation exists, and America’s own National Intelligence Estimate says they don’t believe Iran has an active weapons program either.
