   Operation Desert Storm

Explanation:  It is an operation conducted by US army in the territory of Kuwait with the aim of defeating Saddam Hussein's Iraqi forces and thus liberating Kuwait from the Iraqis. The US defeated Kuwait with its allies for 100 hours in land clashes and battles. At the time, the President of America was Bush, who asked the public to support this war effort and thus undo Vietnam Syndrome. It is a syndrome that is tied to political terminology and refers to the American public's disagreement with military ventures outside of America, as it did in Vietnam. That is why Bush sought public support. In addition to public support, the term is linked to the insecurity of US troops in Vietnam when the war lasted a long time and was exhausting for US troops, while in Kuwait, the enemy was defeated in a very short time and effectively, so the aforementioned Vietnam Syndrome was also nullified in that way.
