Thanks to Nikita S. Khrushchev, says Frank Gibney, world Communism is in far better shape in 1960 than it was in 1953 after Stalin's rule. Conceding that there have been exceptions and setbacks, Gibney credits Khrushchev with pulling off a prodigious public relations trick in achieving throughout most of the world a new Madison Avenue-style ""public image"" for a country whose very name was anathema before he came to power. Gibney, former Time, Life and Newsweek staffer and author of the recent The Operators examines in this readable book Communism'n status in every section of the world. He finds Communism succeeding in Latin America and the Middle East, failing in Western Europe and in Africa. He examines the relations of Russia and Red China. It is Gibney's conclusion that Khrushchev's superficially reasonable tactics are as terrible a threat as Stalin's more obvious aggression, and the U.S. had better get a move on in doing something more than simply reacting to Soviet tactics. An appendix gives a rundown on Communism's status in about every country from Afghanistan to Vietnam.
