Definition of "Madman Theory"
The madman theory is a political theory commonly associated with U.S. President Richard Nixon's foreign policy. He and his administration tried to make the leaders of hostile Communist Bloc nations think Nixon was irrational and volatile. According to the theory, those leaders would then avoid provoking the United States, fearing an unpredictable American response.

President Richard Nixon and his national security adviser Henry Kissinger believed they could compel "the other side" to back down during crises in the Middle East and Vietnam by "push[ing] so many chips into the pot" that Nixon would seem 'crazy' enough to "go much further," according to newly declassified documents published today by the National Security Archive.
The documents include a 1972 Kissinger memorandum of conversation published today for the first time in which Kissinger explains to Defense Department official Gardner Tucker that Nixon's strategy was to make "the other side ... think we might be 'crazy' and might really go much further" — Nixon's Madman Theory notion of intimidating adversaries such as North Vietnam and the Soviet Union to bend them to Washington's will in diplomatic negotiations.

The goal was to get our adversaries to bend to "Washington's will in diplomatic negotiations". I have found no authoritative evidence that the Madman Theory was or was not effective at achieving Nixon's goals.
The Wiki article quotes Scott Sagan as saying the theory was "ineffective and dangerous". The article quoted does make this argument but the same paper says "We have little evidence indicating what the Soviet leaders knew about the U.S. nuclear alert and how they interpreted it." The paper argues from silence and does not address Nixon's goals for ordering the nuclear alert.
Evidence of effectiveness would indicate:
- The Vietnam War ended sooner or on more favorable terms.
- The Soviet Union reduced it's support of North Vietnam or induced Hanoi to make diplomatic concessions.
Is there any evidence that the Madman Theory was effective?
