The statement that is true is "Allowing a foreign leader medical treatment in the United States led to a hostage crisis in Iran."
We are referring to the Iran Hostages Crisis during the United States President Jimmy Carters's administration.
Several rebel students took 60 hostages on the American Embassy in Tehran, Iran, on November 4, 1979. They alleged that the main reason for this action had been the President's Carter permission to allow the deposed Sha of Iran to enter the United States for medical reasons.
