Nah, the myopic focus on Kissinger means ignoring the other culprits in the room, meaning you don't care about the Cambodians beyond using them in political games. The PRC/Vietnamese would have still sponsored the Khmer Rouge into slaughtering them. But then they would be just another in a long list that you could ignore. That's the reason for the whatabotism, the cruelty of ignoring the rest of their plight. As long as it doesn't stain your hands, you'll ignore the slaughter. And from your second point, you admit you don't care about what war crimes Kissinger did abroad only that it hurt soft power. Sounds like a defense of Kissenger to me.
