President Bush's recent claim that weapons of mass destruction have been found in Iraq highlights two disturbing trends in rhetoric from the White House. The first, as we have pointed out , is the Bush administration's record of factual misstatements and distortions. The second is the administration's - and especially President Bush's - history of strategically ambiguous statements that, while technically or arguably true, imply connections between two things which he cannot directly demonstrate.

Just off the road behind fences and berms sits the 23-acre complex of Tuwaitha, Iraq's main nuclear facility. It's now defunct, but it's still a storage area for 3,000 barrels of low-grade uranium and other more dangerous radioactive materials.

The Bush administration claimed, contrary to reports by U.N. weapons inspectors, that Saddam still had an active nuclear weapons program. The Bush administration claimed that the danger of Iraq's handing off nuclear materiel to terrorists was a key reason for regime change.

The administration knew full well what was stored at Tuwaitha. So how is it possible that the U.S. military failed to secure the nuclear facility until weeks after the war started? This left looters free to ransack the barrels, dump their contents, and sell them to villagers for storage.

How is it possible that, according to Iraqi nuclear scientists, looters are still stealing radioactive isotopes?

The Tuwaitha story makes a mockery of the administration's vaunted concern with weapons of mass destruction. The U.S. military hastened to secure the Ministry of Oil in Baghdad from looters. But Iraq's main nuclear facility was apparently not important enough to get similar protection.
