Anyway, I'm voting for the president who didn't support Genocide in East Timor or Bangladesh, thanks.
Bush's foreign policy aims were less sinister and very idealistic, but very costly for the US and very destabilizing to the world thus far.
Nixon's foreign policy aims were ruthless, cold and calculating Realpolitik, but arguably helped stabilize the Cold War chessboard in the West's favor.
Nixon supported genocide in East Timor and Bangladesh. Bush pursued policies that are allowing genocide to happen in the Middle East as we speak. Does intent really matter?
It pretty clearly does in this case, since Nixon was basically supporting the mass killing of Bengalis whereas Bush pretty clearly was not trying to kill Yezidis and Assyrians. That's like arguing Pol Pot and Kennedy are equally responsible for the Cambodian Genocide.*
*Obviously Nixon isn't as responsible as say, Yahya Khan, but still.
