Why did a U.S. military-led coalition attack Iraq in 1991?
A) To defend Saudi Arabia's democratically elected government from unprovoked aggression
B) To defend Operation Desert Storm
C) To remove Iraq's ruthless dictator from power
D) To protect petroleum supplies and respond to reports of atrocities in Iraqi occupied Kuwait
Of these options, the best answer is D. Some of these other answers are in some way related, but none of them is as correct as D.
For example, it is clearly the case that the US was trying to protect Saudi Arabia from unprovoked attack by Iraq. However, it is in no way correct to say that Saudi Arabia's government is democratically elected. Iraq did have a dictator, but the 1991 war was not meant to remove him and Saddam Hussein remained in power for years afterwards. Finally, Desert Storm was the name of the operation, so the war could not have been launched to protect it.
The U.S. military led a coalition of forces to remove Iraq from Kuwait in 1991. The best answer to this question is answer D.
There was a dispute between Iraq and Kuwait over oil supplies. In 1990, Iraq invaded Kuwait and occupied the country. The United Nations gave Iraq until January 15, 1991, to leave Kuwait. When Iraq refused to leave Kuwait by that day, Operation Desert Storm began the next day. Over the next three months, the U.S. led coalition fought and defeated the Iraqi forces. By the middle of April, a cease-fire was declared, ending the fighting. Iraq withdrew from Kuwait.
Iraqi casualties far outnumbered the casualties of the U.S. led coalition. Estimates indicate there were over 100,000 Iraqi casualties. About 25,000 Iraqi soldiers were killed. There were less than 300 soldiers killed for the U.S. led coalition.
Operation Desert Storm was a huge success for the U.S. led coalition.
