“Thank God, the tests on the IR4 and IR2M (centrifuges) have been completed. They were tested for over 12 years. Today we have all the data, and we can easily manufacture them on an industrial scale.” — Ali Akbar Salehi, head of the Atomic Energy Organization of Iran.
The International Atomic Energy Agency (IAEA) was not allowed to inspect or monitor Iran’s military sites where nuclear activities were most likely being carried out. Among the many concessions that the Obama administration gave the Iranian government, one was accepting the Iranian leaders’ demand that these military sites would be out of the IAEA’s reach.
Due to this surrender, various high-profile Iranian sites such as the Parchin military complex, located southeast of Tehran, were free to engage in nuclear activities without the risk of inspection.
Once the authoritarian, anti-Semitic and anti-American government of Iran possess a nuclear bomb, no amount of actions will be able reverse the catastrophe.
