In chaos theory, the butterfly effect is the sensitive dependence on initial conditions in which a small change in one state of a deterministic nonlinear system can result in large differences in a larger state. In other words, a butterfly flapping its wings in Texas can cause later a typhoon in the Japanese Sea.
But not for the Vietnam War and the 1968 Tet Offensive, Obama would still be a Community Organizer and hanging out in Chicago bath houses, but the “Butterfly Effect” of the 1968 Tet Offensive made it possible for Barack Hussein Obama, a homosexual Muslim Communist, to be elected to the highest office in the land.
During the Vietnam War, the 1968 Tet Offensive resulted in the annihilation of Viet Cong units throughout South Vietnam and was a disaster for the Communist insurgency; it never recovered from its loses. This Tet Offensive was a coordinated “Do or Die” attack by every Viet Cong unit in South Vietnam on the night of January 30 and the morning of January 31, 1968 that simultaneously struck every South Vietnamese City, village, and military installation in an attempt to win the war in one country wide attack; they failed and they paid the price for their failure; they died.
The war was carried on after Tet 1968 by invading North Vietnamese, and North Vietnam could never move sufficient troops down the Ho Chi Minh Trail to ever hope to defeat the United States effort in South Vietnam, so they resorted to another Communist tactic; they lied.
1968 was a Presidential Election year in the United States, and the Communist Party USA attempted to use the Tet Offensive to influence the election by claiming it was a Communist victory and the war was lost. This American Communist Party organized an anti-war movement and assembled enough strength through this movement to seize control of the Democrat Party that summer during the 1968 Democrat Convention in Chicago.
These Communists attempted to nominate a Presidential candidate who would end the war and they failed, but the Communist Party USA still retained control of the Democrat Party, and this Party managed to elect enough Leftists to Congress to cut funding for the Vietnam War and the war was then lost, so in this way the 1968 Tet Offensive was indeed a Communist victory.
After using the Tet Offensive to gain control of the Democrat Party, the Communist Party USA never lost control of the Democrat Party, and when a few decades later they managed to elect an avowed Marxist Communist, Barack Hussein Obama, to the Presidency of the United States, it made the 1968 Tet Offensive the greatest Communist victory of all times.
