For two generations up through the mid-1980s, many thought we were losing the Cold War, even in early 1989, few believed that Poland`s solidarity movement could win, that the Iron Curtain would come down, that the Baltic states could be free, that the second of the 20th century`s great evils, communism, could be vanquished without war, but it happened and the West`s great institutions, NATO and the E.U., grew to embrace 100 million liberated Europeans.

Realism as a foreign policy doctrine means basically you don't care about values; you consider them a luxury, and it leads to a kind of acquiescence in spheres of influence. Now, spheres of influence sound good if you're a graduate student, or a certain kind of - an academic with a certain habit of mind.
