Why did us and coalition troops try to stop iraq’s invasion of kuwait?

Hey dude!
It was principally for the only reason of the wars in this world, money. Kuwait was one of the richest nations in oil although its size. Kuwait had one big buyer, the United States. When Iraq conquered kuwait they feared about they're national economy and also in the middle east. 

The correct answer is "  it was believed that the dispute emerged in 632 just after the death of the prophet muhammad."
