What was the Iraq Liberation Act of 1998? Why was it signed into law?

Okay how would we feel if the UN came in and tried to question us about our stuff. Iraq was set up and this country is just being picked on since we knew we could take over it without lifting a finger. Since we are too afraid to attack iran or north korea because their armies would be a challenge and you know us Americans we like everything easy and fast. Iraq I believe was a war of boredom and trying to act like the US was in charge of the world still. Plus everyone answering this question. Did you really believe that Iraq was a threat to us? If you did then please convince me that it was the right thing to do. GO USA!!!!!!
