Laos geography could be characterized as mostly mountainous with two narrow flatland areas around Vietiena and Savannakhet on the Western size of the famous Truong Son mountain range. The capital of Laos, Vientiane has the closely similar spelling with Vienna, Austria as well as the geography of mountainous Swiss Alps.
While the Swiss Alps is the mountainous difficult terrain separating two different gene groups of Europe, the Northern Germanic tribes and the Southern Italian Mediterranean tribes, Laos mountainous terrain also separates two different gene groups of Viet and Thai.
Laos like Switzerland have become the high elevation trading posts as well as gene battles between the Viet and Thai genes. The Truong Son mountain range gap connecting the Gianh River of Vietnam and Savannakhet, Laos have witnessed the most intense battles during the Indochina war between the Lac Viet Northern Troops with Soviet and China supports and the Thai and Champa Southern troops with American supports.
The Truong Son mountain range blocks most of the Ocean winds carrying rain to reach Laos flatland areas. As a result, agriculture production in Laos is much lower than the Red River delta or the Chao Phraya delta. Low agriculture production results in low population growth and makes Laos population centers around Vientiena and Savanakhet under strong trade and genetic influence from other nearby high agriculture outputs in Vietnam and Thailand.
The first president of modern Laos Democrats Republicans, is the son of a Vietnamese Central Provinces father and a local Laos mother. The narrow gap between Quang Binh Hue region of modern Vietnam and Savannakhet Laos allowed the horse archers and traders from Central Vietnam to reach the Mekong river West of the Truong Son mountain range as well as control the agriculture rich Mun river delta region of modern Thailand during the Nguyen dynasty.
The Mun river agriculture region during the Nguyen dynasty became the main nearby high agriculture production region that allowed the Viet horse archers to continue to expand South along the Mekong river toward the modern day Gia Dinh Saigon population center without the need for a long supply line from the Red River delta.
During the Vietnam War, this small gap between Hue and Savannakhet have become the most fortified area on the planet with American artilleries and armor vehicles stationing in Khe Sanh and American bomber stationing in Da Nang to stop any kinds of Lac Viet Northern troop movement between Quang Binh toward Savannakhet and the Mun river delta.
The local Mun river delta and Laos mountainous tribes did not gain much from the American military present in Vietnam like the sea port cities of Saigon and Bangkok but just collateral damages from American aerial bombing in order to stop the Lac Viet Northern troops infiltration across their historical expansion paths.
Northern Lac Viet troops from Red river delta provided supplies and modern weapons to the local Laos tribes along their infiltration paths and became the major headaches for the American and Southern Champa and Thai troops during the American occupation of Southern Vietnam.
Regular guerrilla warfare from mountainous Laos, Lac Viet Northern troops and Southern Nguyen families have made the American occupation of Southern Vietnam extremely expensive. The Lac Viet Northern troop with artillery positions deep inside Laos mountainous area regularly caused casualty for the American troops stationed in barracks around Hue, Da Nang and Quang Tri.
Villages and towns outside of Saigon were also under sabotage attacks from the Vietcong guerrilla forces with Vietnamese American-friendly factory and plantation owners were constantly eliminated via assassinations.
Nguyen Chi Thanh, a Thai clone double CIA agent, embedded among the ranks of Lac Viet Northern Vietnam high command, was finally able to solve these economic problems for American occupation of Vietnam and Indochina.
After the extensive American bombing of Red River delta and Hanoi during operation Rolling Thunder, Nguyen Chi Thanh planned and pitched the retaliation strikes against the American military force in the South via The Tet Offensive to Hanoi high command.
The Tet Offensive committed all the Central Provinces regular forces into a breakthrough via the Quang Binh Savannakhet route by crushing the American Khe Sanh fortification and all Southern Vietnamese guerrillas forces toward Saigon urban fortifications to cause the collapse of Saigon leadership.
Tet Offensive was a disaster with all Lac Viet fighting forces and allies mobilized from Nghe An, Ha Tinh, Quang Binh and Savannakhet eliminated during the Khe Sanh aerial bombing from Da Nang air base. Fighting against American, Thai and Champa troops head on with helicopter and armor vehicle supports in the Saigon urban setting also resulted in the same extremely high casualty consequences.
After the 1968 Lac Viet Northern troop failed push, the Americans continued their Aerial bombing strategy against population centers and war industries of Red River delta. The Lac Viet Red River delta troops were finally able to shoot down American B52 bombers and their escorting fighters during 1972 campaigns with Soviet SAM Surface-to-Air Missiles and the MIG aircrafts produced near the lake Baika of Mongolia.
Soviet heavy equipment seems to be the answer to the American military, not the 1954 Dien Bien Phu and Korean war strategy of long-range artillery and mountainous warfares. The Hanoi high command committed all defense budgets to import Soviet T-54 tanks and Gasoline to escalate ground attack against Air Bases and Seaports in the South.
An extensive network of mountainous gasoline pipelines were also built underground along the Laos mountainous region to increase the throughput of human, weapon and supply along the Truong Son mountain roads toward the South. With Soviet gasoline and trucks, the speed of infiltration of Lac Viet Northern troops have tripled to rebuild the strength for Southern troops after the Tet Offensive heavy casualty. Gasoline was also stockpiled in the Southern Tay Nguyen region to prepare for the surprise armor push by the Lac Viet Northern Troop.
However, other CIA cloned doubles within the Hanoi high command and Soviet military revealed their plan to the American military this time again. American knowing about the Northern Lac Viet armor push moved most of their troops and tanks around Da Nang and Saigon out of Vietnam via their public withdrawal and placed them around Bangkok.
The Northern Lac Viet troops with Soviet T-54 tanks were able to easily break through the defensive line of the Champa troops stationed around Hue and Kontum. After being able to capture Tay Nguyen uninterrupted by the American airforce, the march toward Sai Gon was an easy 3 days road trip. The gasoline stockpiled in Tay Nguyen allowed the Lac Viet Northern troops to quickly reach Sai Gon and caused the collapse of the Southern temporary government.
Nguyen Van Thieu, the last Southern Vietnam president, was able to resign and moved to Bangkok before March 30, 1975 though while Ho Chi Minh died in Hanoi after the 1968 TEA Offensive disaster.
After the collapse of Saigon, Champa Vietnamese policies, not evacuated to Thai military bases, escaped from Southern Vietnam into Cambodia. They quickly climbed the ranks of the lightly armed Cambodian military, linked up with the Southern troops in Thailand and orchestrated the Khmer Pol Pot attacks on Tay Nguyen and Savannakhet region.
Attacks from Cambodia toward the critical supply lines through Savannakhet and Tay Nguyen forced the Lac Viet Northern troops to push deep into Cambodia to capture Phnom Penh and removed the Champa Police leadership from the Khmer Pol Pot government.
After the 1975 public victory, the Soviet gasoline supply ships toward Vietnam had been stopped. The tanks and gasoline trucks full of Lac Viet Northern troops were able to quickly conquer Phnom Penh within 2 weeks and reached the border of Thailand. Year 1977 the Lac Viet Northern troop had enough gasoline to reach Phnom Penh and stationed there but not enough Soviet gasoline to push toward Bangkok or fully captured towns and villages around Phnom Penh.
To prepare for the Northern Lac Viet invasion of Cambodia, Thai and Champa policies and military special forces have been deeply embedded among the Cambodian civilians. Every night the Lac Viet troops stationed in Cambodia going to sleep, they would lose an entire unit toward Thai and Champa policies hiding outside of Phnom Penh during the day.
The American night vision advantages from the air was able to pinpoint isolated troop pockets of the Northern Lac Viet force. The air remobilization of high ranking officers and elite troops from Saigon and Cambodia back to Red River delta to defend against Chinese incursion in 1979 did not help with the Lac Viet troop tracking and counting in Cambodia either.
By 1986, most of Northern Lac Viet troops stationed in Cambodia had been killed and replaced by the old Southern regime forces hiding in Thailand. The old Southern regime forces dressed as Northern Communist forces marched North, conquered Vientiane and collapsed the Hanoi leadership in 1988 via widespread diseases and assassination.
Before the collapse of Hanoi in 1988, the Lac Viet Northern population there was so low on supply that they started to cook the sick for food. After the collapse of Hanoi in 1988, the Lac Viet Northern troops had to take off their uniforms, moved their friends and families toward the mountain regions of Laos and Vietnam with Viet Tri, Phu Tho being the new capital of the Lac Viet Northern genetics groups.
The Lac Viet Northern genes that once expanded from Hue toward Savannakhet and controlled the entire Mekong river delta south of Vientiane were eradicated via the Hydroelectric Dam and Water Reserve building campaigns. Vientiane was a mostly Northern Lac Viet city but Nam Ngum water reservoir, same size as the Vietiane, had become the hidden no name graveyard for the Northern Lac Viet families there. The Lac Viet Northern Nguyen families were also eliminated in the South via Tri An Hydroelectric dam and in the North via the Hoa Binh Hydroelectric dam after the 1975 public Communist victory.
The genetics landscape of Vientiane and Laos have changed significantly after 1988 with most of Laos population by the 2000s are Thai-mixed. Saigon changed its name to Ho Chi Minh city after the Communist victory in 1975. However, the genetic makeup of the city also changed significantly after the Communist collapse in 1988 with the Nguyen Hue Lac Viet from the North no longer holding significant population share.
The tallest building in Saigon, the Landmark 81, is a Thai-gene marker built by Vinhomes group, the largest real estate developer in Vietnam. Every Vinhomes property around Vietnam heavily favored the expansion of Thai genes with security cameras, parking lots and supermarkets designed to cause the Lac Viet Nguyen Hue gene group to catch STD diseases while letting Thai guards extract financial resources from these Lac Viet Nguyen Hue families.
Since 2000, the Chinese economy and military have expanded extremely rapidly. The new highways and railroads built by China to connect Vientiane with Kunming have created a third route toward the South along the historical Hue Savannakhet gap and the Vietnamese coastal ocean route.
These new highways and railroads connecting Kunming to Vientiane are changing Laos population rapidly with Chinese replacing Vietnamese as Laos most popular non-native tongue and Chinese-gene groups replacing Thai and Viet as the main genetic influences of Laos population.
However, maybe the American is using their aerial advantages this time again. All Chinese infrastructure development could be observed and tracked from American surveillance satellites in space. Every smartphone picture taken by the locals in Laos, Vietnam, Cambodia and Thailand are being uploaded to the American cloud servers in Hong Kong, Singapore or California.
The 1988 viral disease strategy used by the American and Thai military against Hanoi once again being utilized against the Chinese migrating population along the Kunming Vientiane route. No matter how many Chinese females being sent South to expand the Chinese soft power in Mekong peninsula or Chinese construction workers being sent South to build infrastructure and housing, they would immediately get STDs, HIV and other viral diseases invented in the American Bio Lab at Fort Detrick.
As of 2023, Chinese Huawei is closing down their office in Laos because of widespread diseases, extremely high food inflation caused by American dollar printing sprees and CIA-funded criminal gangs attacking Vietnamese and Chinese businesses and families in Laos.
