Episode Notes:

When an American submarine sank an Iranian frigate on March 4, the attack sparked vigorous debate about the law of naval warfare and what the United States sought to achieve. In her article for War on the Rocks, Jennifer Parker explained how the law of naval warfare applies to the sinking of the IRIS Dena. Kerry talks with Jennifer about the legal debate and the contemporary value of the law of naval warfare — and also about the strategic implications of the attack in the Indian Ocean.
