The man who negotiated the first SALT treaty with USSR in 1969, which somehow held until START II in 1993 which never really took effect, sadly. He opened up relations between USA and China in 1971. He led the peace process between Vietnam and the US (leading to his Nobel Peace Prize).
This article is absurd bullshit in how much guilt it lays on Kissinger. For instance, it alludes that the Cambodian genocide was due to Kissinger, while in reality, it was Pol Pot 100%. Even if there are circumstances that lead to committing genocide, country leaders are not unthinking animals with no free will. Pol Pot decided to do this, it’s on him, and it’s one of the many atrocities communist countries have done. You cannot just bullshit your way out of that, no matter how much you like communism.
