Even if the reports were overstated, are ALL of the warheads missing the same parts, or could we be looking at a situation where cannibalization could provide a small number of working nukes?IIRC, "Viktor Suvorov" (real name: Vladimir Rezun), the defector who wrote several good books about the Soviet Army, stated in the 1980s that the one thing that limited the USSR's strategic arsenal was an acute shortage of fissionable material, and that a lot of warheads were loaded with radioactive waste instead of plutonium.
They might be missing the same component--the important one...
The above is my "gut read" on the topic.
If that is the case, then we're still dealing with a nasty situation. "Dirty bombs" won't rack up as high a body count, but they'll still be pretty good at ruining someone's day.
Then comes the question of how much material Saddam has in his hands already, and if that could cause problems.
