The second Gulf of Tonkin attack that triggered the Vietnam War never actually happened — documented evidence

🟢 CONFIRMED

On August 4, 1964, the USS Maddox reportedly came under a second attack by North Vietnamese torpedo boats. President Johnson used this to push the Gulf of Tonkin Resolution through Congress, giving him unlimited military authority. NSA documents declassified in 2005 confirmed the agency deliberately manipulated signals intelligence to fabricate the second attack. Secretary McNamara later admitted the August 4th incident did not occur. The resolution led to the deaths of 58,000 Americans and millions of Vietnamese.
