Okay... here goes *deep breath*

Saddam Hussein and Osama Bin Laden had NOTHING to do with each other. In fact, they hated each other. So attacking Iraq to find Bin Laden makes 0 sense. However, even if you say it was unconnected the only WMD's you're going to find there are the one's that GEORGE BUSH SR. gave to Hussein to fight against the Iranians. Go look it up if you don't believe me. The war was a simple excuse to invade Iraq and take its oil. That's it.
