Please read some of the UN Resolutions regarding Iraq. A simple search on Google will find exactly what you need.
The inspectors are NOT looking for a smoking gun. The resolutions place squarely upon the shoulders of Saddam the responsibility to provide proof either the location or destructions of chemical and biological weapons the UN KNOWS Iraq was in possession of.
The placement of the burden of proof upon the inspectors is intellectually dishonest and smacks of hidden agendas.
Here is a jumping off point for anyone interested in reading some of the resolutions:
Per the language in the resolutions, it is incumbant upon Iraq to provide proof of destruction of contraband weapons, not incumbant upon the UN or USA to proove they exist.
So my question is, why do intelligent people continue to look for a “smoking gun”? If they are not interested in what the letter AND spirit of the resolutions really are, then why are we interested in ANYTHING the UN has to say in the matter?
