Libya showed American and British inspectors a significant quantity of mustard and bombs

I say, Colonel K., do you have any Grey Poupon?

of course they mean mustard GAS ... I believe it causes your lungs to fill up with fluid and you drown / suffocate ... (at least that's what our engineering chem professor stated in college) ...

A blister agent, very persistent. Causes large, painful blisters on contact. Inhaled it produces blisters in the lungs and airway (hence the "drowning"). A very old technology but very deadly.
