The thing I've learned when talking about international politics is that, Logic, goodwill, kindness, etc. rarely have anything to do with it. They're simply masks and disguises for the true intent.
Politicians and national leaders will do anything, and I do mean anything that will benefit their nation, and their nation alone in either the short or long term. Potentially, this benefits themselves personally. Doing the right or moral thing matter absolutely jack...in most cases doing the Legal thing isn't a deterrent either.
You see, most nations are selfish to the extreme...no scratch that...ALL nations are selfish to the extreme...compare them to spoiled 5 year-old little boys. Always bickering, always wanting more...
You see, Iraq isn't a threat to the U.S...at least not on an international level. The situation is simple:
U.S. benefits (at least in the short run) from a victorious war with Iraq:
-war stimulates economy.
-Iraqi oil in U.S. control...now THAT's power
-A U.S. friendly puppet Arab state in the Middle East...other than Israel.
So, how do they 'market' this war...why, just like every other war in the late twentieth century of course! Market it by creating (or making up out of thin air) an excuse.
In this case, the excuse is "weapons of mass destruction", or "Saddam is a national threat to the U.S." I mean nevermind that such statements are false and hypocritical to the extreme, but most people won't take the 10 seconds it takes to logically analyze these statements (without logic, remember?), those that actually have the mental capacity that do so, will buy into the govt. propaganda because they have no sources that tell the other side of the story (or choose to ignore the information), and finally those that do figure it out, are far and few between, and get shot down from irrational flames spit out from those that do believe what the government shovels them.
And then, of course, there's just good' 'ole nationalism (aka as ignorance/arrogance/racial bias/hatred/etc.).
So, my advice to you, Zhaneel, when attempting to analyze why the U.S. is going to war...just don't.
It's an excercise in futility, and even if you do figure out the answer, you realize that 99% of the people out there don't give a rat's oink...
This all reminds me of a concept from Dune:
Most people out there are animals. On a few of us are truly human.
Disclaimer: This is MY opinion solely. Yes it is hypocritical to criticize others as being biased when I myself am biased by certain views, but the first step to objectivity is recognizing your bias...it's just that I have yet to make that second step...(and probably never will in my lifetime)...
