Rudy Giuliani, in Foreign Affairs.
„Idealism should define our ultimate goals; realism must help us recognize the road we must travel to achieve them. The world is a dangerous place. We cannot afford to indulge any illusions about the enemies we face. The Terrorists’ War on Us was encouraged by unrealistic and inconsistent actions taken in response to terrorist attacks in the past. A realistic peace can only be achieved through strength.
A realistic peace is not a peace to be achieved by embracing the „realist” school of foreign policy thought. That doctrine defines America’s interests too narrowly and avoids attempts to reform the international system according to our values. To rely solely on this type of realism would be to cede the advantage to our enemies in the complex war of ideas and ideals. It would also place too great a hope in the potential for diplomatic accommodation with hostile states. And it would exaggerate America’s weaknesses and downplay America’s strengths.”
