Answer :
The correct answer is C) distrust.
The word that best characterizes the ambassador’s perspective of American foreign policy is distrust.
In the excerpt, we can read “The foreign policy of the United States is characterized…by a striving for world supremacy. This is the real meaning of the statements of President Truman…that the United States has the right to rule the world.”
Nikolai Novikov, USSR Ambassador, clearly denotes distrust in his words because he considers that the United States wants to dominate and control the world. In his letter of September 1946, he is not trusting the foreign policy of the United States. Situations like this after World War II and during the Cold War generated a lot of tension in the relationship between the Soviet Union and the United States.
