Well, they were essential parts of a machine that is used to create enriched weapons-grade uranium. This can be used to produce more than enough uranium to build nuclear bombs, which can then be attached to missiles, which in turn can be launched in 45 minutes.
Happy now?
The interesting bit isn't that he hid WMDs in his backyard. The interesting bit is that he was able to hide some pretty dangerous stuff related to Iraq's illegal nuclear-weapons program for <b>12 years</b> without anyone finding out. This leads to questions about the possibility of hiding other essential bits of equipment, and even the possibility of hiding tons of chemical weapons.
And I for one would NOT like to see him build nukes and launch them.
