I was wondering....

The attack attempt on President BushSr,
The Riyadh bombing
The Khobar Towers bombing
The USS Sullivans attempt
and
The USS Cole attack

..those all used plastic explosives-of which I know very little, BUT I wonder if it might be possible to corroborate the type of explosives used in each attack? That is, wouldn't it be incredible if they all used explosives matching the 380tons of missing explosives from Saddam's Iraq? If the bomb residue from Al Queda attacks matched Saddam's explosives....isn't that literally a form of smoking gun?

I've tried to find out more on the explosives used in each attack, but gotten nowhere, and I'd LOVE some input form this site as y'all really seem to know your stuff (or you lie like pro-poker players selling used cars :D ).

Thanks in advance
