You really don't know what you're talking about. Tet started us down the road to surrender.
Militarily, Tet was decidedly an Allied victory, but psychologically and politically, it was a disaster. The offensive was a crushing military defeat for the Viet Cong and the North Vietnamese, but the size and scope of the communist attacks had caught the American and South Vietnamese allies completely by surprise. The early reporting of a smashing communist victory went largely uncorrected in the media and led to a psychological victory for the communists. The heavy U.S. and South Vietnamese casualties incurred during the offensive–and the disillusionment over the early, overly optimistic reports of progress in the war–accelerated the growing disenchantment with President Lyndon B. Johnson’s conduct of the war.
