It just makes you feel so proud to be an American, doesn't it?
Detailed evidence has emerged of Israel's extensive use of US-made weaponry during its war in Gaza last month, including white phosphorus artillery shells, 500lb bombs and Hellfire missiles.
In a report released today, Amnesty International listed the weapons used and called for an immediate arms embargo on Israel and all Palestinian armed groups. It called on the US president, Barack Obama, to suspend military aid to Israel.
The human rights group said those arming both sides in the conflict "will have been well aware of a pattern of repeated misuse of weapons by both parties and must therefore take responsibility for the violations perpetrated".
The US has long been the largest arms supplier to Israel; under a 10-year agreement negotiated by the Bush administration the US will provide $30bn (£21bn) in military aid to Israel.
As you may remember, use of white phosphorus (considered a war crime when used against civilian populations) was denied by the Israelis. Doctors treating wounded civilians blamed the shells for horrific burns.
