>What, then, are the main motives for the war, in your opinion? You seem to indicate that oil is one of them.

Think it's not accurate to say "motives", rather to say "politics". It goes far beyond just oil.

You will find many stuff around about PNAC ("Project for the New American Century") and some intentions of US government, such as "Hawks to Bush: Military spending is inadequate" (http://www.finalcall.com/artman/publish/article_446.shtml).

Of course if some people can make good money with wars, it's good business for them...
