Twenty years after the fall of the Berlin wall, former Soviet Union President Mikhail Gorbachev tells CNN's John King it was "a very important event" in which "the voters could vote in a competitive election." He also comments that United States President Barack Obama is "facing a very difficult challenge" in his current role, though his election was "unprecedented." Gorbachev also suggests that it is not necessary for additional American troops to be sent to Afghanistan.
