Since the revolution, Iran's first priority has consistently remained the survival of the regime. Iran also seeks to become the strongest and most influential country in the Middle East and to influence world affairs.
Iran has installed several cascades of more powerful centrifuge models in production lines, where they have steadily increased both the size and enrichment level of Iran's uranium stockpile. This progress increases the risk of secret sites – permitting them to be smaller and easier to hide. Iran has used such sites to carry out illicit activity in the past and they continue to pose the greatest nuclear weapon risk.
