"I especially appreciated Rev. Moon’s commitment to the fight against Communism. From his own first-hand, personal experience and out of his religious convictions, he understood how tragic a political and social blight that movement had been. I had been in East and West Berlin the week the Berlin Wall was erected in August 1961 and had visited communist Poland in 1965. Unfortunately, many of my liberal academic colleagues did not understand the full nature of the threat as did Rev. Moon. I was impressed with the sophistication of Rev. Moon’s anti-communism. He understood communism’s evil, but he also stood ready to meet with communist leaders such as Mikhail Gorbachev and Kim Il Sung in the hope of changing or moderating their views."
