Recent documents show that the hardcore branch of the US policy during the Vietnam war, was playing dangerous games with North Vietnam and the Soviets, in order to drag the other side to negotiations.
We see today a similar game played by the neocons in Ukraine and Asia-Pacific. In the new Cold War, neocons are playing more dangerous games with Russia and China, as they try to persuade that they will not hesitate to proceed in a nuclear strike against both their rivals, because they see that the Sino-Russian bloc threatens the US global sovereignty.

“Nixon’s and Kissinger’s Madman strategy during the Vietnam War included veiled nuclear threats intended to intimidate Hanoi and its patrons in Moscow. The story is recounted in a new book, Nixon’s Nuclear Specter: The Secret Alert of 1969, Madman Diplomacy, and the Vietnam War, co-authored by Jeffrey Kimball, Miami University professor emeritus, and William Burr, who directs the Archive’s Nuclear History Documentation Project. Research for the book, which uncovers the inside story of White House Vietnam policymaking during Nixon’s first year in office, drew on hundreds of formerly top secret and secret records obtained by the authors as well as interviews with former government officials.”
