Iranian–Israeli relations have shifted from close ties between Israel and Iran during the era of the Pahlavi dynasty to hostility since the Islamic Revolution led by Ayatollah Ruhollah Khomeini. Iran has severed all diplomatic and commercial ties with Israel, and its government does not recognize Israel as a country and refers to its government as the "Zionist regime." The land is referred to by Iran as "Occupied territories." Due to recent rhetoric between Iran and Israel, development of nuclear technology, and funding of the groups Hamas and Hezbollah, tensions have risen between the State of Israel and the Islamic Republic of Iran, especially after the election of the hardline Mahmoud Ahmadinejad in 2005.
