Today is the 26th anniversary of the failed hostage rescue attempt in Iran which resulted in death of Eight American servicemen.
The fall of the late Shah of Iran in 1979 turned Iran to a anti-American hotbed for a while, and the crisis got worse when a group of radical islamist-marxist individuals supported by the Islamic regime leadership occupied the US embassy in Nov, 4th 1979 and took more than 60 American diplomats hostage for more than a year.
As an Iranian, I am sorry for the mistreatment of the American nationals in Iran but the issue of hostage taking will remain in history of Iran as a dark and shameful spot for which we owe an apology to the Americans.
The Atlantic Monthly recently published a series of articles, pictures and video clips on the hostage crisis which can be seen at The Atlantic Online web site.
For more information, you may want to view James Bancroft's personal web page which is looking at the issue from a personal point of view.
Update1: I forgot to mention the Canada's role in helping couple of American hostages to flee Iran during the crisis. Canada did help prepare fake documents for bunch of American diplomats to get away.
