Today America's leaders, ignoring the example of Dr. Kissinger, have abandoned realpolitik. Otto von Bismarck, the Iron Chancellor who united Germany coined the term. In its original German it means "the politics of reality." According to the tenets of realpolitik, foreign policy has only one purpose: the security of the state. Instead our leaders have subverted it to crusading for the touchy feely advancement of causes and ideologies.
