The Mujahedin Khalq Organization (the MKO) has apparently had only one goal since the Islamic revolution in Iran, in 1979: the overthrow of the Islamic Republic. Regardless of its real capacity to achieve such an aim or not, for decades, the group has strained to take opportunities of regional and political ups and downs into its aim, even though in most cases there is no true relation between what is going on in the region and what the group is trying benefit from. It seems the group is confused.
An instance of the group’s opportunistic nature was recently seen in the so-called testimony given by Maryam Rajavi in the US Congress where she presents the overthrow of the Iranian government as the main solution to fight ISIS!
Daniel Larison of the American conservative Magazine writes about Rajavi’s weird recommendation to the West: “The plan to bring down ISIS by toppling Iran’s government, then, is little more than the latest chapter of group’s 50-year history of monomaniacally trying to install itself atop the Iranian government.” 
He adds, ”This obviously has nothing to do with combating or understanding ISIS, and allowing her to speak at such a meeting just lends a totalitarian cult a platform from which it can promote its own warped agenda. Inviting Rajavi demonstrates exceptionally poor judgment, and her testimony will make a farce of the proceedings tomorrow.’’ 
“It sounds counter-intuitive—Iran’s aid to the Iraqi government and various Iraqi militias, after all, is widely credited with stopping ISIS’s advances there—but not when you know about the MEK’s tortuous past,’ suggests Ali Gharib of the Nation. “Over the years, the MEK has been nothing if not opportunistic; animated by the twisted logic that the enemy of its enemy is its friend, the group seizes whatever political angle is fashionable at the moment to bring them relevance (Congress is happy to oblige).” 
engage in diplomacy with Islamic Republic.
Eldar Mamedov who has served as a political adviser for the social-democrats in the Foreign Affairs Committee of the European Parliament (EP) and is in charge of the delegation for inter-parliamentary relations between the EP and Iran, analyzes the MKO’s part to obstruct diplomacy with Iran. He refers to the Cult’s large-scale efforts to demonize the Iranian Government and to derail any relation between the EP and Iran. Nonetheless, he asserts the group’s lobbying efforts to accomplish its aim has so far failed. On the contrary to the group wishes, Islamic Republic has become an important ally for the Europe in fighting ISIS.
“A growing realization of the converging interests between the EU and Iran accounts for this dramatic change,’’ Eldar Mamedov submits.” This time, the discussions in Brussels were not so much focused on traditional European concerns, such as Iran´s nuclear program and human rights, as on the situation in the Middle East.” 
Mamedov concludes, “In a scenario of rapidly disintegrating states and spreading terrorist threats, European officials are discovering that Iran is among the most stable and predictable state actors in the region.” 
In his opinion, the EU´s foreign policy supremo Federica Mogherini mentions the advantages of engaging with Iran because she “definitely doesn´t share the Saudi narrative of Iran being the root of all tumult in the Middle East. In fact, she sees the nuclear deal with Iran as a gate opener for engaging Iran on the regional issues, including in Syria and Yemen, which is an anathema to Saudis."
The MKO leaders, namely Maryam Rajavi would be disappointed to know that “officials from the Mogherini-led European External Action Service (EEAS) now discuss the possibility of a regional dialogue with Iran, which is a sharp departure from her predecessor Catherine Ashton, who approached Iran as an exclusively nuclear problem.” 
Despite the MKO’s harsh opposition against the visits of the Iranian Parliamentary delegation to EP, the visits took place anyway. The visit of the Iranian MPs to Brussels is considered by Mamedov as “another sign of changing times in the Middle East.”
Mamedov notifies, “Although a wholesale rapprochement between the EU and Iran may still be some way off, inter-parliamentary diplomacy has the potential to build trust, bridge differences, and eventually make a re-alignment possible,” inviting US Congressmen to join such peaceful policy.
It seems that Maryam Rajavi and her supporters should work harder to survive the new geopolitical and regional undercurrents.
