This was before I was in the USAF:
On 31 December 1967, the Department of Defense announced that 864,000 tons of American bombs had been dropped on North Vietnam during Rolling Thunder, compared with 653,000 tons dropped during the entire Korean War and 503,000 tons in the Pacific theater during the Second World War.
and Rolling Thunder simply didnt work...the flow of men and supplies increased year after year when RT was started, culminating in the massive TET offensive in 68...bombing the same bridges year after year...bombing camp fires in the jungle...Johnson actually picking the targets from the Oval Office..the whole thing was just nuts...
