From Gabbard's webpage...seems pretty clear eyed to me.
“The history of the United States relationship with Iran is rooted in, and defined by, a decades-long policy of regime change, which began with the CIA-led overthrow of democratically-elected Prime Minister Mohammed Mossadeq in 1953 in order to keep U.S.-backed Mohammad Reza Shah in power. This ultimately sparked the 1979 Islamic Revolution which grew from strong opposition to years of U.S. interventionist policies in Iran and throughout the region. As Iran’s new anti-U.S. government took power, our threats of intervention grew and Iran started its nuclear program as a direct response to defend against the possibility of another U.S.-led intervention and regime change plot.”
Decades later, our CIA under the control of the Commie/Muslim Brennan and backed by Obama, the Clintons and their buds in the CIA/DOJ/FBI attempted to have a regime change to oust our elected President, Trump. They are still trying with their impeachment bs in the house.
