This fact sheet illustrate Iran's aggressive policies over nearly four decades, and
categorically refutes the persistent lies promoted by the Tehran regime.

1. The Iranian regime is the world's number one sponsor of terrorism. The Quds Force and other
state and state-sponsored organizations actively engage in and support terrorist organizations
abroad, such as Hezbollah, Hezbollah Al-Hejaz (Saudi Hezbollah), Asa'ib Ahl al-Haq (League of
the Righteous) in Iraq, and a number of sectarian militias, including Houthis in Yemen. Iran
has supported and conspired with other terrorist organizations, such as Al-Qaeda. Iran has
harbored Al-Qaeda leaders, some of whom still enjoy sanctuary in Iran. Iran has been condemned
by the United Nations and many countries. International sanctions have been imposed on it.
