The munitions addressed in the report were produced in the 1980s, Maples said. Badly corroded, they could not currently be used as originally intended, Chu added.
While that's reassuring, the agent remaining in the weapons would be very valuable to terrorists and insurgents, Maples said. "We're talking chemical agents here that could be packaged in a different format and have a great effect," he said, referencing the sarin-gas attack on a Japanese subway in the mid-1990s.
This is true even considering any degradation of the chemical agents that may have occurred, Chu said. It's not known exactly how sarin breaks down, but no matter how degraded the agent is, it's still toxic.
