Al Jazeera investigates the shocking truth behind a deadly Israeli attack on a US naval vessel. In 1967, at the height of the Arab-Israeli Six-Day War, the Israeli Air Force launched an unprovoked attack on the USS Liberty, a US Navy spy ship that was monitoring the conflict from the safety of international waters in the Mediterranean.

Israel is the only state to have legalised torture through a ruling by its own Supreme Court. An expert who has documented these violations since 1983 says, “What the world knows today is less than 5% of what has actually occurred.”

When it comes to selling weapons, the United States is in a league of its own: more than 40 percent of all arms sold worldwide come from US companies.
