America's Greatest Ally

Just don't sail near their claimed "territory", or their government might murder you for no reason. This, according to the US State Department:

The security environment within Gaza, including its border with Egypt and its seacoast, is dangerous and volatile. U.S. citizens are advised against traveling to Gaza by any means, including via sea. Previous attempts to enter Gaza by sea have been stopped by Israeli naval vessels and resulted in the injury, death, arrest, and deportation of U.S. citizens. U.S. citizens participating in any effort to reach Gaza by sea should understand that they may face arrest, prosecution, and deportation by the Government of Israel. [...] On May 31, 2010, nine people were killed, including one U.S. citizen, in such an attempt.

Call me old fashioned, but this usually isn't a disclaimer you have to make with your supposed greatest ally in the history of the universe.
