The Cold War, from 1945 to 1989, was a wild Bacchanalia for arms manufacturers, the Pentagon, the C.I.A., the diplomats who played one country off another on the world's chess board, and the global corporations able to loot and pillage by equating predatory capitalism with freedom. In the name of national security, the Cold Warriors, many of them self-identified liberals, demonized labor, independent media, human rights organizations, and those who opposed the permanent war economy and the militarization of American society as soft on communism. 

That is why they have resurrected it.

The decision to spurn the possibility of peaceful coexistence with Russia at the end of the Cold War is one of the most egregious crimes of the late 20th century. The danger of provoking Russia was universally understood with the collapse of the Soviet Union, including by political elites as diverse as Henry Kissinger and George F. Kennan, who called the expansion of NATO into Central Europe "the most fateful error of American policy in the entire post-Cold War era."
