The UN Security Council passes Resolution 678 by a vote of 12 to 2, on November 29, 1990, authorizing member states to use "all necessary means" to compel Iraq to withdraw from Kuwait by January 15, 1991, or face military action.
Only Cuba and Yemen voted against the resolution, with China abstaining. The last time a UN authorization of the use of force had occurred was in 1950, when the Security Council approved military action against North Korea after its unprovoked attack on South Korea. Iraq did not comply, leading to the Iraq war (Code name Operation Desert Storm) which started on January 17, 1991.
