The Vietnam Standard Oil War!!
The Rockefeller-controlled Pentagon used the excuse of the war to drop bombs in the water and listen to the echo in order to locate the underwater oilfields.
Herbert Hoover, later to become President of the United States, worked for a huge mining corporation that exploited the world of resources. He lived for years in Russia where there were huge amounts of American mining interests until 1917 when the Commies took over and booted Hoover & the miners out, and nationalized or TOOK OVER the AMERICAN digs. Hoover had done a study however, way back when that showed that one of the world's largest oil fields ran along the coast of the South China Sea right off French Indo-China, now known as Vietnam. This was before offshore drilling had been invented and before a man named George Herbert Walker Bush was to become the CEO of a world-wide offshore drilling company.
In 1945, Vietnam was still a colony of the French. Laurence Rockefeller, it appears, had given the extensive store of weapons to Ho Chi Minh (who had been our NORIEGA in the region during WORLD WAR II. or like OSAMA BIN LADEN had been OUR paid warrior against the Russians in AFGHANISTAN. We salaried those guys, and they became BLOWBACK for us. ) We used HO with the hope that Vietnam would drive out the French so that Standard Oil would be able to take over the as yet undeveloped offshore fields. But in 1954, Vietnamese General Giap finally defeated and drove out the French at Dien Bien Phu with weaponry provided by the U.S. Ho Chi Minh renegged on the deal since he could read too, (more than read, huge college education in Moscow.) Ho was well aware of the Hoover resource report and knew there was a vast supply of oil off the Vietnamese coast.
In the 1950's a method of undersea oil exploration was perfected which used small explosions deep in the water and then recorded the sound echoes bouncing off the various layers of rock below. The surveyor could then determine the exact location of the arched salt domes which hold the accumulated oil beneath them. But if this method were used off the Vietnam coast on property Standard didn't own or have the rights to, the Vietnamese, the Chinese, the Japanese and probably even the French would quickly run to the United Nations and complain that America was stealing the oil, and that would shut down the operation. So they put on their thinking caps and what did they come up with?
