Answer:
Allowing a foreign leader medical treatment in the United States led to a hostage crisis in Iran.
Step-by-step explanation:
The hostage crisis in Iran took place from November 4, 1979, to January 20, 1981. During this period, fifty-two American diplomats and citizens were held hostage after a group of Iranian college students took over the American Embassy in Tehran. The crisis was partly motivated by the fact that the United States admitted Shah Pahlavi for cancer treatment. This was seen as a rejection of Iran's new government and a sign of complicity with the old regime.
