This just blows me away.
You shouldn't be the NYT is blowing smoke - nothing new. 380 tons is a very miniscule amount compared to how much high explosives Saddam had in his total munitions inventory.
RDX is a very common high explosive used by world militarizes. It's common as dirt.
RDX can be found in Air Intercept Missiles, Air-to-Ground Missiles, C4 demo blocks, and many more weapon systems. What do you think are in those RPGs that are shot at our troops?
