This is a non sequitur, troll. The first thing has nothing to do with the second thing...

the UN could compell him (Saddam) to do so (comply). That Resolution has never been rescinded to the best of my knowledge.

The first thing says that the UN could compell him to do so.

The Congress of the United States voted to give George Bush the authority to prosecute the war if saddam failed to comply with the terms of the UN Resolution.

The second thing says that the US Congress voted to give Bush the authority to prosecute the war if Saddam failed to comply.

Since it was the UN that issued the resolution you refer to, only the UN has the authority, under the terms of the resolution, to prosecute the war if Saddam fails to comply. The US Congress has no authority to give Bush the authority, under the terms of the resolution.
