The first of these complicating factors have to do with the fact that the United States and the Islamic Republic of Iran share a mutual distrust and hatred for one another. This distrust and hatred have been born out of a very long history of government subversion and US-supported puppet regimes within Iran. After the Islamic Revolution in the 1970s, the situation was made worse between the two countries as the United States embassy personnel were paraded in front of international media with blindfolds and held within Iran for a total of 444 days. This mutual distrust has led to a breakdown in understanding between the two nations both believe the other has dubious motives in either seeking to acquire nuclear material or seeking to deprive the other of such acquisitions.
