“Ever since Iranian terrorists imprisoned American embassy personnel in Tehran early in November, these 50 men and women in their safety, their health, and their future have been our central concern. We’ve made every effort to obtain their release on honorable, peaceful, and humanitarian terms, but the Iranians have refused to release them or even to improve the inhumane conditions under which these Americans are being held captive… The militants controlling the embassy have stated they are willing to turn the hostages over to the government of Iran, but the government has refused to take custody of the American hostages. The Iranian government can no longer escape full responsibility by hiding behind the militants at the embassy. It must be made clear that the failure to release the hostages will involve increasingly heavy costs to Iran and to its interests.” President Jimmy Carter, April 7, 1980
