Saddam wasn't co-operating... the others were not seeing that 12 years was an inordinate amount of time...
The UN is in-effective as of 2130 EST March 19, 2003. They can't even agree to disagree and move along on *A* path... some of the members don't even care *WHAT* is going on... *IN* Iraq.
That time and date was the beginning of the end of the UN. Some may argue it was in 1998.
Pretty soon, it'll be "good" ole colonialism setting in...
If you think it wasn't about Saddam it wasn't... it is about UN not being able to resolve anything and enforce it.
