… justice comes from power, and power is only possible from a degree of ruthlessness most of us can’t abide. The tragedy of political life is the conflict between the limit of good intentions and the necessity of power. At times this produces goodness. It did in the case of Lincoln, Roosevelt, and Reagan, but there is no assurance of this in the future. It requires greatness.
