Why Is the US-Iran Relationship so Filled With Animosity?

France allowed the Ayatollah Khomeini to live in exile SGT (Join to see) until he built up support in Iran to return to his homeland in 1979. Shah Pahlavi was our ally and Iranian pilots trained in this nation until the Iranian revolution took over Tehran and then the rest of the nation.
The radicals stormed our embassy and took the staff hostage while the crowds chanted that the USA was the Great Satan for 444 days [Fifty-two American diplomats and citizens were held hostage for 444 days from November 4, 1979, to January 20, 1981, after a group of Iranian students belonging to the Muslim Student Followers of the Imam's Line, who supported the Iranian Revolution, took over the U.S. Embassy in Tehran.]
The Revolutionary Guards are Iran's radicalized military which is exportable to foment Shia Islam wherever they go from Yemen to Lebanon and Syria.

To start would be the overthrow of the Shaw of Iran by The religious zealots then taking Hostages from the American Embassy. The anti Western attitude against the US as well as other Western nations and also Israel. Sending the modern pro Western nation of Iran centuries back into the past with their intolerant extremism. The constant threat, lies and mistrust of present Iran as a nation towards the civilized world. Their moves on the development of nuclear weapons. That's just a start on the list.
