In your opinion what did Kissinger do that amounts to genocide of his own people, not to mention the string of assassinations of his domestic opponents?
Again, I am not taking a stance since I haven't done enough research, just explaining why theoretically someone could think that Kissinger committed crimes against humanity without killing any Americans or even violating American laws.
Perhaps you may wish to familiarize yourself with the ethnic and religious differences between the Serbian forces commanded by Milosevic and the persons they killed.
"In his diary in March 1969, Nixon's chief of staff, H. R. Haldeman, noted that the final decision to carpet bomb Cambodia 'was made at a meeting in the Oval Office Sunday afternoon, after the church service'.
In his diary on 17 March 1969, Haldeman wrote:
Historic day. K[issinger]'s "Operation Breakfast" finally came off at 2:00 pm our time. K really excited, as is P[resident].
And the next day:
K's "Operation Breakfast" a great success. He came beaming in with the report, very productive. A lot more secondaries than had been expected. Confirmed early intelligence. Probably no reaction for a few days, if ever. "
Did you missed the part of your own source where it says that the operation targetted North Vietnamese Army bases within Cambodja?
Does that count as a genocide at all, let alone a worse genocide than Milosevic's Bosnian genocide?
Wrong. Milosevic was trialed for his role on the Bosnian genocide, which included the assassinations of Bosnian serbs.
Even if you believe that although Milosevic was president of Yugoslavia then no breakaway Yugoslav republic can be counted as his people, you can't turn a blind eye to Bosnian serbs.
The reason? The people of that small, freshly liberated country were on the verge of holding their first democratic elections, and dangerously close to choosing a left-wing party to govern them, of their own free will.
That being said perusing his wikipedia page should give you many things to read about.
And of course Zia al-Haq in Pakistan.
