Its pretty simple to see whats happening if you read carefully between the lines.
The US know a rough date when Saddam will go fully nuke or biochem capable. My guess is Q1 2003. The US have to attack before then, if they don't then the whole thing is off. Its likely that post Q1 2003 any attack by the US would meet some sort of NBC response from Saddam, and the US analysts would know the casaulties would be massive on the US side.
So its either now or never.
So what if its never? Well, Saddam will go from strength to strength. Most of Arab countries are scared of him. Not only because of his NBC capabilities and willingness to use them, but because of the fact he has toejamloads of supports in these countries.
So his first move will be to re-acquire Kuwait. Plus a little Saudi territory is my guess. This will be his 'testing' of the waters. If the US and Saudi's fail to respond in force, then he will see this as an indicator of his strength. At this stage he would have considerable NBC capability and its doubtfull the US will have any interest in dying en masse.
Next move is a choice - Israel or Iran, at the right moment (ie Israelis shoot some palestianians) he provokes the Israeli's into an all out war. The Egyptians and Syrians allie with Iraq and blow the toejam out of Israel. The war potentially goes nuke but Iraq is prepared to go down that avenue IMHO.
Sounds kind of airey-fairey but this guy has attacked other nations without remorse, as well as used bio and chem weapons without a second thought.
Saddam wants power, wants $$$$, and wants land. Hes playing a waiting game, the longer he drags the issues out the more options he has to weazel into the position of power.
