George F. Kennan was an American diplomat in Moscow after World War II. In 1946, he sent what became known as "the long telegram" of his advice about what the USA needed to do about the Union of Soviet Socialist Republics (USSR). It really was a LONG telegram at 8,000 words. (Think of how many Twitter messages that would be today!)
In those days, everyone feared an ultimate confrontation between the USA and the USSR -- that the Cold War would someday explode into a massive heated conflict between the superpowers. Kennan, in Moscow, had much foresight to see the internal problems the USSR had. He advised not pushing the conflict too much, but instead just try to "contain" the Soviet Union and wait for their system to collapse under the weight of its own problems. Kennan was right. It took almost 50 years, but eventually the communist system in the USSR fell apart. [The Union of Soviet Socialist Republics came to an end in 1991.]
C. The charter’s call for the end of apartheid would have been threatening to the South African government.
The Soviets were proclaiming themselves as communist, though the reality was not as the communism truly says a state should be run. If the Soviets practiced the textbook communism, then everyone in the society would have been equal. Everyone was going to earn the same amount of money and get the same things necessary for life without any problem. The economy would have been self-sustaining and that was going to be supported by excellent planning. There were not going to be social classes, but everyone would have been in the same class. The Soviets did pretty much everything wrong with those ideas, and in all fairness the human nature just doesn't allow for something like that to exist.
Mikhail Gorbachev was hated by the hardline communist. The main reason for that was that he was trying to make the country slightly more liberal, more open to the world and to modernization. That was seen as treason of the communist ideology by the hardline communist so they were against all of that.
