Israel and the nuclear program of Iran
The government of Israel believes that if the Islamic Republic of Iran achieves the development of nuclear weapons, the existence of Israel will be in serious danger and this regime will be the first target of a possible nuclear attack by Iran. Benjamin Netanyahu, the prime minister of Israel, who is mentioned as one of the supporters of Israel's "preemptive strike" on Iran's nuclear facilities, has repeatedly emphasized in official speeches that "all the risks are small and insignificant compared to the risk of Iran's nuclearization." The Iranian government has repeatedly emphasized that the country's nuclear program is for peaceful purposes such as energy production and medical issues, and is not seeking to build nuclear weapons.
