Daylia, I've posted this on two other treads but here it is again.
Resolution 678 was passed on November 29, 2990, soon after the Iraqi invasion of Kuwait. Resolution 678
"Authorizes Member States co-operating with the Government of Kuwait .. to use all necessary means to uphold and
implement resolution 660 (1990) and all subsequent relevant resolutions and to restore international peace and
security in the area."

Resolution 687, passed after the liberation of Kuwait, requires disarmament of Saddam Hussein and reaffirms
resolution 678. Since resolution 687 reaffirms 678, and since 678 allows Member States to use "all necessary
means" to implement "subsequent relevant resolutions", it follows that resolution 678 allows the United States (a
Member State) to use force to disarm Saddam Hussein.

Resolution 1441, yet another resolution requiring Saddam to disarm, also reaffirms resolutions 678 and 687. So ..
same logic applies."
