Fifty years ago, on April 30, 1975, North Vietnamese military units surged into Saigon, the capital of South Vietnam, forcibly reuniting the country, thus ending 20 years of conflict. Scenes of North Vietnamese T-54 tanks crashing through the gates of the Doc Lap Independence Palace were among the poignant closing episodes of the Vietnam War. Soon, the massive outpouring of refugees became a searing reminder of the fast-ending conflict.
The original US plan of limited counterinsurgency to thwart communist attacks morphed into a full-scale war. For the US, a cardinal mistake was deposing nationalist South Vietnamese President Ngo Dinh Diem. The coup d'etat orchestrated by President John F Kennedy and the CIA deposed Diem's government on Nov 1, 1963, putting the country on a perilous trajectory of incompetent military governments over the next decade.
The US massively reinforced troops from 1965 until 1971, when there were 535,000 Americans in Vietnam. President Richard Nixon began a process of "Vietnamisation" whereby the South Vietnamese Army (ARVN) would transition to do the fighting to defend their country. The US military commitments would be reduced; the last American combat troops left the country in March 1973.
During the conflict, the Americans were not alone in supporting the South Vietnamese; there were military units from Australia, Thailand, and, among the best, more than 50,000 South Korean combat forces. A decade of war cost nearly 58,000 American lives, with more than 2,500 MIAs. Millions of refugees fled.
More than 2 million Vietnamese died on both sides. Significant political divisions in the US during the war persisted for decades. Now, half a century later, it's not the time to "re-fight or re-litigate" the war, but rather revisit to assess the lingering "What ifs?" Recall that Henry Kissinger's flawed 1973 Paris Peace negotiations produced an agreement whereby communist North Vietnam and reasonably democratic South Vietnam would coexist as separate entities, as they had since 1954 following the French colonial period.
But the North Vietnamese army (NVA) and their local Viet Cong proxies gained military advantage through the "ceasefire in place agreement", allowing the North an unquestionable foothold, given their forces already controlled substantial territory. This fact offers an eerie echo with plans for a Ukraine ceasefire, a ceasefire in place for Russian troops. An international settlement ensured that the status quo of North and South Vietnam, divided by the DMZ at the 17th parallel, would legally form the dividing line much as the 38th parallel separated both North and South Korea since 1953.
Both sides had pledged not to attack the other, at least on paper. The collapse in 1975 came like dominoes; NVA probing attacks in February from Boun Me Tout and Pleiku in the Central Highlands proved surprisingly successful. The Soviet-supplied Hanoi communists gambled and launched a major offensive with 30 divisions of regulars, during which South Vietnamese towns and ARVN units crumbled, often ineffectively, without a fight.
By April, the NVA were near the gates of the capital, Saigon. The rest is history as NVA tanks and units captured the city on April 30. The curtain fell on the Indochinese wars.
Contrary to popular myth, the US military was not retreating from embattled Saigon in the last days; rather, the formidable logistics and economic support apparatus in South Vietnam was being hastily evacuated. American combat forces were withdrawn two years earlier. But Vietnam is not a war, but a country of 100 million people.
Let's say the status quo held as in Korea. Even in 1974, South Vietnam's economy outshone the communist North. North Vietnam's now forcibly reunified Socialist Republic of Vietnam suffered under a corrupt and incompetent socialist economy until 1986 when Do Moi market reforms began to replace the moribund Marxist system.
China, the US and the European Union are major trading partners. Massive foreign investment has flourished in recent years. Former South Vietnam would likely have emerged as a Southeast Asian "Tiger Economy" by the late 1970s, a moderately prosperous export economy with an upward trajectory.
Today, Vietnam boasts 6% GDP growth, and per capita income is near $5,000. Vietnam is a top 10 trading partner of the US, with $149 billion in two-way trade; yet Washington faces a $123 billion trade deficit! Nonetheless, 50 years after a united Vietnam, the country is reasonably prosperous but retains a communist authoritarian system. Who would have thought?
