Vietnam War Didn't Happen

It's the year 1954. The Viet Minh won the first Indochina War after the Battle of Dien Bien Phu and officially ended French involvement in Indochina. In Gevena, Switzerland, the Geneva Conference is being signed. The agreement temporarily separated Vietnam into two zones, a northern zone to be governed by the Viet Minh, and a southern zone to be governed by the State of Vietnam, then headed by former emperor Bảo Đại. A general election will be held by July 1956 to create a unified Vietnamese state. In addition, the Kingdom of Cambodia and the Kingdom of Laos were created as well. However, after Ngo Dinh Diem took power in southern Vietnam, he refused letting the State of Vietnam (which he renamed the Republic of Vietnam) to take part in the elections to re-unify the country. Therefore the elections were never organized. What happened next is the bloody Vietnam War which millions of people died. But what if the elections did take place and Vietnam were unified? What if the Vietnam War Didn't Happen? Most of the information will be written here.

POD
Ngo Dinh Diem was never born and Bao Dai remained the head of state of southern Vietnam until the elections. Also, for some reason the United States support the elections unlike OTL.

Aftermath
The reason why Diem didn't let the elections happen (and why the US supports Diem's decision) is because he knew he would lose, and North Vietnam would won. Reports of the CIA showed Eisenhower that ~80% Vietnamese citizens would vote for Ho Chi Minh, because he's like the George Washington of Vietnam. The majority of Vietnamese citizens were farmers or workers, who hated French colonism, and Ho Chi Minh's Viet Minh were the one to end it.

So if the elections happened, Vietnam would be unified under the communist government without blood and violence. There would still be Vietnamese refugees fleeing the country like the Catholic minorities, but it would not be as serious as OTL.

Even though a communist Vietnam will be a Soviet ally, Vietnam would not make an enemy out of the US, because Ho Chi Minh seek help from the US for Vietnamese independance before he became a communist. Vietnam will join the NAM earlier than OTL and perhaps not closing itself from the West.
