Answer:
One international foreign policy achievement of President Carter's administration was:
C. Establishing the SALT II agreements with the Soviet Union.
1. SALT II refers to the Second Strategic Arms Limitation Treaty, which was signed between the United States and the Soviet Union during President Carter's administration in 1979.
2. The treaty aimed to limit the number of strategic nuclear weapons possessed by both countries and reduce the risk of nuclear war.
3. SALT II built upon the earlier SALT I treaty and included provisions for further arms control measures, such as restrictions on the development of new missile systems.
4. By establishing the SALT II agreements, President Carter demonstrated his commitment to arms control and promoting stability in the U.S.-Soviet relationship.
5. Although the treaty was ultimately not ratified by the U.S. Senate due to various factors, its negotiation and signing marked a significant foreign policy achievement for President Carter's administration.
In summary, one international foreign policy achievement of President Carter's administration was the establishment of the SALT II agreements with the Soviet Union, which aimed to limit nuclear weapons and promote stability in the U.S.-Soviet relationship.
