A plan better left secret

During the 1968 presidential campaign, at the height of the Vietnam War, Richard Nixon allowed the nation to believe that he had a “secret plan” to end the war. Once elected, the plan remained secret, and Nixon later denied that he had a secret plan. However, it has also been said that the secret plan consisted of seeking help from the Soviet Union, which was supplying the North Vietnamese.
If so, it’s understandable that Nixon would want to keep the plan secret, and eventually to deny its existence. The notion that our arch-enemies, the Soviets, would bail us out of Vietnam was ridiculous, and Nixon presumably would have been embarrassed to be publicly associated with that sort of naivety.
James Baker and his group apparently are considerably harder to embarrass.
