The article throws light on the UN role in the Gulf crisis. The Iraqi
invasion of Kuwait on August 2, 1990, was a clear-cut breach of intern
ational law and there was no doubt that the UN Security Council had a
formal reason for acting. However, formalities alone cannot explain th
e commitment and activity performed by the SC members in this particul
ar crisis. The 12th resolution of the Iraq-Kuwait crisis authorized th
e use of ''all necessary means''. Thus it represented the closest the
organization has come in using the system of economic and military san
ctions according to the Charter. The article is concentrated on the qu
estions of why the members of the Security Council were able to find c
onsensus in taking these measures, and how the UN system functioned du
ring the crisis.
