What's this about mustard gas?

The sarin isn't a big deal, but what's this about mustard gas? Where can I find more info on this finding (besides Faux)?

1. Sarin is a much bigger deal than mustard gas

Sarin is a nerve gas. Mustard gas is just a blister agent and has been around since WWI.

2. No, it isn't.

Sarin (Iraq's sarin anyway) has a much shorter shelf life. It was known that Iraq probably had old shells full of degraded sarin in chemical dumps throughout the country (which is where the insurgents probably got it, according to Blix).

Mustard gas is a bigger deal because if it was of Iraqi origin then Iraq probably did lie to inspectors, and retained stockpiles of it. Furthermore, the gas was probably still viable as a weapon.
