Based on the excerpt, President Truman planned to take the use of atomic weaponry on Japan if Japan refused Allied terms of surrender.
Answer: Option B
<u>Explanation:</u>
The Potsdam declaration directed Japan to surrender during the second World War when the document was issued by President of U.S. Harry S. Truman, Prime Minister of UK Winston Churchill and China's chairman named Chiang Kai-Shek. This ultimatum was given to Japanese armed forces and otherwise, consequences were entire devastation of the nation.
The technology which boosted President Truman to declare an alternative for Japan was the usage of the atomic bomb and related weaponries on their nation which was possessed by the United States although this warning was not declared in official documents.
The hostage crisis in Iran took place over a period of 444 days, during which a group of Iranian students took 66 diplomats and citizens of the United States of America (USA) hostage. The crisis began on November 4, 1979 and lasted until January 20, 1981.
The crisis was described by the Western media as a "revenge and mutual incomprehension". In Iran, the taking of hostages was widely seen as a blow against the United States. In the United States, and in general the West see hostage-taking as an outrage on the part of the Islamist movement that violated the principle of international law on immunity and inviolability of diplomats and their embassies.
In 1980, the death of the Shah (July 27) and the invasion of Iran by Iraq in September made Iran more prone to the resolution of the hostage crisis. In the US, Carter lost in November 1980 the presidential re-election for the benefit of Ronald Reagan. Most analysts believe that Carter's mistakes in trying to solve the crisis played an important role in his defeat.
Some believed that the Constitution did not give the new federal government the ability to restrict inherent rights, so no list of those rights was necessary. Others worried that if the rights were listed, they would invariably forget some and the list would ever be incomplete. Finally, the argument was that the states each had their own constitutions, too, and that rights were best protected at a state level.
