A group of U.S. citizens is rejecting the Obama administration’s attempt to thwart their aid mission to the Gaza Strip, which threatens to leave them stranded in Greece. They are set to sail from a Greek port on a U.S.-flagged ship called “The Audacity of Hope,” part of an international humanitarian flotilla carrying aid for Gaza’s 1.5 million Palestinian residents. Flotilla members are taking part despite Israeli threats to intercept their ships. Nine people were killed in an Israeli attack on the first aid flotilla just over a year ago. The Audacity of Hope passengers have called for the U.S. government’s help in ensuring their safe passage. But instead, the Obama administration has told them not to set sail and even warned them they could face punishment back home. Secretary of State Hillary Clinton suggested Israel would have the right to use force to prevent the ships’ passage. The State Department called the flotilla "irresponsible and provocative" and warned that U.S. delegates could face "fines and incarceration.” We play an excerpt from a press conference when State Department spokesperson Victoria Nuland is repeatedly questioned about the Obama administration’s threat, but refuses to answer whether the U.S. considers the Israeli blockade of Gaza to be legal.
