Here's an interesting post on Jimmy Carter's impact on the Shah of Iran and his eventual downfall to the Islamic totalitarian, terrorist-supporting government that exists today. Probably, much of this information needs to be vetted, since this isn't exactly a known resource, but it paints an interesting picture.
In accordance with the pleasant US-Iran relations then-existing, President Carter spent New Year's Eve in 1977 with the Shah and toasted Iran as "an island of stability in one of the more troubled areas of the world". Nonetheless, between 1975 and 1978, the Shah's popularity fell due to the Carter administration's misguided implementation of human rights policies. The election of Mr. Carter as president of the United States in 1976, with his vocal emphasis on the importance of human rights in international affairs, was a turning point in US-Iran relations. The Shah of Iran was accused of torturing over 3000 prisoners. Under the banner of promoting human rights, Carter made excessive demands of the Shah, threatening to withhold military and social aid. Carter pressured the Shah to release "political prisoners", whose ranks included radical fundamentalists, communists and terrorists. Many of these individuals are now among the opponents we face in our "war on terrorism".
When the Shah was unable to meet the Carter Administration and British demands, the Carter Administration ordered the Central Intelligence Agency to stop $4 million per year in funding to religious Mullahs who then became outspoken and vehement opponents of the Shah. Unfortunately, the Shah's efforts to defuse the volatile situation in Iran failed, despite the grant even of free and democratic elections. Confronted with lack of US support and unleashed Mullah fury, the Shah of Iran fled the country.
Subsequent to the Carter Administration's ill-conceived foreign policy initiative, Iran is now a dungeon. Ayatollah Khomeini's dictatorship executed the Shah's prisoners, predominantly communist militants, along with more than 20,000 pro-Western Iranians. Women were sent back into servitude. Citizens were arrested merely for owning satellite dishes that could tune to Western programs. American diplomats were taken hostage, and the Soviet Union invaded Iran's eastern neighbor Afghanistan as a result of this chaos, allowing it to secure greater influence in Iran and Pakistan. The struggle against the Soviets in Afghanistan, and the defeat of this invading Superpower with help from the United States under President Reagan gave rise to the radicalization and emergence of Muslim zealots like Osama bin Laden. Moreover, within a year of the Shah's ouster, Iran on its western flank was locked into the Iran-Iraq War, in which the U.S. sided with secular Iraq and its military dictator Saddam Hussein.
Maybe a bit of a stretch, although it's compelling:
Thus Jimmy Carter's misguided implementation of human rights policies not only indirectly led to overthrow of the Shah of Iran, but also paved the way for loss of more than 600,000 lives, Iran's rule by Ayatollahs, the Iran-Iraq War, Iraq's Invasion of Kuwait and Desert Storm, the Soviet invasion of Afghanistan, the Taliban, Al Qaeda, Osama bin Laden, and the mass murder of Americans and destruction of the World Trade Center towers on September 11, 2001.
