Why did united nations try to stop Iraq from taking over Kuwait in 1990?

The United Nations sought to stop Iraq from invading Kuwait in 1990 to uphold international law and maintain regional stability. Iraq's invasion threatened the sovereignty of Kuwait and set a dangerous precedent for aggression in the Middle East. The UN aimed to protect the rights of nations and prevent the escalation of conflict, ultimately leading to the Gulf War, where a coalition of forces intervened to restore Kuwait's independence.
