What if the South Won the Vietnam War?

In our time line the South Lost after the US withdrew its troops and equipment from the area after Gerald Ford used it as a campaign promise and the South quickly fell after this occurred.

Lets speculate otherwise, we can have 2 possible outcomes either Vietnam is completely unified which is unlikely or a North South divide is created much like in Korea which is most likely to be the outcome.

We don't know how this could be done a brief armistice could have been signed like in Korea or the complete take over of the North could be a legitimate result. But enough about how and more about after.

After the Vietnam War the US supported Vietnam state would be treated much like South Korea with it having a similar if not larger force than what was stationed in Korea due to the direct border with China in the need for defense or attack. Its economy would be limited much like how South Korea was at the end of the Korean War with large amounts of damage to infrastructure and rural population centers so a US sponsored repair scheme would be instituted. Its actual GDP could be twice the size of that of Communist Vietnam today which would be $342 Billion or even 3x that which would be $513 Billion. Vietnam company brands would be prominent in the Western World like that of Sony(Japanese) and Samsung(South Korea) as brands seen on Shelves on that of Western Europe and North America.

The Political field would be more intense as China would still push for its massive Naval Water claim into the South China Sea. It's biggest Allies apart from the US would be Japan and South Korea as they would share a common goal in securing their interest in South Asia and South East Asia alike. ASEAN (The Association of South East Asian Nations) would be far more important to this Vietnam than Ours as while our Vietnam has a surprisingly high amount of distrust and fear towards China despite both being Communist states; so this Vietnam would rely on it. its neighboring states of Cambodia and Laos would treat Vietnam with Stagnant feelings most likely if a conflict doesn't rise in between the time of the South Winning and 2017.

This is a small implantation as many others factors would have influenced the condition of a Split or united Vietnam
