Will they or won't they?

ABC News is reporting that, once again, drums filled with suspicious chemicals have been found in Iraq. Preliminary tests indicate they may contain nerve gas and a blister agent, but there'll be nothing definitive for at least a couple of days. One thing officials are noting is that this time, there are some missiles and warheads near where the chemicals were found, along with "partially looted vehicles ... with dosage charts inside."

One thing I did notice in the article, though is that everyone is trying to be very careful to stress that these findings are preliminary and, as has happened before, may turn out to be something else when all the tests are in.
