As a member of the United Nations Security Council for 1990 and 1991, Yemen abstained on a number of UNSC resolutions concerning Iraq and Kuwait and voted against the ...use of force resolution. The vote outraged the U.S. Saudi Arabia expelled 800,000 Yemenis in 1990 and 1991 to punish Yemen for its opposition to the intervention.
