For decades the US, Israel, and Saudi Arabia have been trying to take advantage of the chaotic situations created by civil wars. They did this by training and equipping proxy forces. The result of this catastrophic tactic has so far been huge casualties and loss of lives in the region.
One of the most instrumental proxy forces used against the Iranian Government is the Mujahedin Khalq Organization (the MKO/ the Cult of Rajavi). The group itself has made too much effort to gain the support of the US, Israel, and Saudi Arabia although its hostility towards the Islamic Republic seems to be convincing enough for the Saudis and Zionists.
The MKO in its turn gives enough credit to its supporters for their warmongering agendas in the Middle East including Yemen, Syria, and Iraq.
For the time being, the US is fighting a complicated proxy war in Syria. According to the New York Times, “Insurgent commanders say that since Russia began air attacks in support of the Syrian government, they are receiving for the first time bountiful supplies of powerful American-made antitank missiles.” 
The propaganda media of the Cult of Rajavi publishes the news of US-Saudi backed forces of the ISIS and other insurgents in Syria and Yemen reporting their alleged progress, every day. The Cult of Rajavi cannot conceal its happiness of the recent visit between the US Secretary of State and his counterpart in Saudi Arabia because they might go on the same path to back the MKO against the Islamic Republic, some day.
The MKO’s propaganda accuses the Islamic republic of intervening in the internal affairs of the countries in the region while it is cheering the US and Saudi for their military and financial aid to fighting rebels and terrorists in the region.
Change will definitely come to nations in different ways but not by a destructive cult with a dark history of terror against civilians and violation of human rights against its own members. Furthermore, since this group is hated by Iranians due to its treason during the eight year war with Iraq and collaborating with Saddam, it does not have any place among people of Iran. 
An October 7, 2015 hearing before the US Senate Committee on Armed Forces (SASC) titled, “Iranian Influence in Iraq and the Case of Camp Liberty,” served as a reaffirmation of America’s war mongers’ commitment to back the terrorist MKO.
During the hearing, former US Senator Joseph I. Lieberman, former US Marine Corps Commander and former Supreme Allied Commander Europe General James Jones, USMC (Ret.), and Colonel Wesley Martin, US Army (Ret.) provided testimony to back the MKO terrorists. 
The Bangkok based American journalist Tony Cartalucci writes, “All three witnesses made passionate pleas before a room full of nodding senators for America to continue backing not only MEK terrorists currently harbored on a former US military base in Iraq, but to back groups like MEK inside of Iran itself to threaten the very survival of the government in Tehran.” 
Cartalucci lists the MKO’s violent attacks:
”Admissions to the deaths of the Rockwell International employees can be found within a report written by former US State Department and Department of Defense official Lincoln Bloomfield Jr. on behalf of the lobbying firm Akin Gump in an attempt to dismiss concerns over MEK’s violent past and how it connects to its current campaign of armed terror – a testament to the depths of depravity from which Washington and London lobbyists operate.
“To this day MEK terrorists have been carrying out attacks inside of Iran killing political opponents, attacking civilian targets, as well as carrying out the US-Israeli program of targeting and assassinating Iranian scientists. MEK terrorists are also suspected of handling patsies in recent false flag operations carried out in India, Georgia, and Thailand, which have been ham-handedly blamed on the Iranian government.” 
He also confirms the MKO’s cult-like attitude referring to Council on Foreign Relations Senior Fellow Ray Takeyh who described the group a “cult-like organization” with “totalitarian tendencies.” 
Cartalucci criticizes the speakers of the hearing, “Not once is any of this backstory mentioned in the testimony of any of the witnesses before the senate hearing, defiling the memories of those who have been murdered and otherwise victimized by this terrorist organization. The de-listing of MEK in 2012 as a foreign terrorist organization by the US State Department is another indictment of the utter lack of principles the US clearly hides behind rather than in any way upholds as a matter of executing foreign policy.”
Once more, Cartalucci warns about the notorious policy paper “Which Path to Persia? Options for a New American Strategy toward Iran” that eagerly discussed the potential of the MKO as a proxy force against Iran, in 2009. 
Belen Fernandez of Al Jazeera criticizes the double standards of the West on terrorism. She announces the Islamic Republic as victim of terror. “While Iran is portrayed in Western and Israeli circles as a relentless supporter of terrorism worldwide, the conference focused on a less politically convenient reality: that of Iran as a victim of terror,” she states. As an enlightened journalist who has interviewed victims of the MKO terror attacks in Tehran, Fernandez condemns the US’s hypocrisy on the issue of terrorism. ”Indeed, when it comes to terrorizing people, the “land of the free” beats the Islamic Republic, hands down. But the victory goes largely unreported in mainstream circles because double standards have become standard operating procedure.”
