The correct answer is false.
It is false that weapons of mass destruction were discovered by United States troops in Iraq.
One of the reasons that the US President gave to invade Iraq was the belief that Sadam Hussein had weapons of mass destruction hidden somewhere in Iraq. The United Nations had not found any of them and ask the United State for the clearance and the decision of the Security Council of the United Nations before thinking of an invasion. But President Bush did not wait, the troops invaded Iraq, and they did not find any weapon of mass destruction.
