And that matters precisely how? The Hussein regime was to account for and destroy all existing WMD's. The fact that these are pre-1991 is more condemning of his government, not less. It means that they have concealed records of these weapons in addition to the weapons themselves for over 12 years in violation of the cease fire agreed to in 1991.
If they had been of 1998 or later make, the argument could have been made that weapons inspections worked in the past and he had only been able to renew efforts since the weapons inspectors were removed. The fact that he was able to hide these munitions is clear evidence that weapons inspections had not worked nor were ever going to work.
This is a great arguement and I wonder why the Bush43 administration has not used it.
All US nuclear weapons are pre-1991 also. They still make good fireworks.
Would be nice if our media had the same attitude.
