As the co-leader of the Mujahedin Khalq Organization, Maryam Rajavi, calls on the West for more sanctions against Iran, her leading sponsor in the US Congress is demanding new sanctions to pressure Iranian government. The US-MEK campaign is paired with Israeli propaganda against Iran.
Immediately after a seven-month extension in talks between P5+1 was announced, Maryam Rajavi started to blame the West for not being firm on Iran. According to Rajavi “Exercising firmness and tightening the sanctions” is the only option to deal with Islamic Republic that should be followed with supporting the MKO as the alternative for the Iranian regime.
On the other side of the world, Rajavi’s paid advocates also launched their own campaign to obstruct nuclear talks. Even before the ink dried on the extension agreement in Vienna, skeptics in Washington were demanding new sanctions to pressure Iran`s rulers, reported Reuters. 
The American Israel Public Affairs Committee, long regarded as one of the most effective lobbying groups in Washington, called on Congress to take up sanctions legislation. Members of AIPAC are mostly found among advocates of the MKO in the US government. You can find certain names on both lists of recipients of the MKO and AIPAC contributions such as Robert Menendez, Lindsey Graham and Carl Levin.

Senator Robert Menendez, Senator Lindsey Graham and Senator Carl Levin are three of the long list of the MKO supporters who receive large amounts of speaking fees to speak on behalf of the group. They are paid for their luxurious trips to attend the MKO’s rallies around the world. News and videos of their advocacy for “the cult of Rajavi” are available on the group’s websites.
Reuters reported that Sen. Robert Menendez, the chairman of the Senate Foreign Relations Committee from Obama’s Democratic Party stopped short of calling for new sanctions immediately, but said: "The cycle of negotiations, followed by an extension, coupled with sanctions relief for Iran has not succeeded.” 
Opponents of the Iranian government including the MKO and American-Israeli warmongers disrespect the fact that the alleged Iranian nuclear program was basically a forged story made by Israeli Intelligence service and published by the MKO propaganda arm. The investigative journalist Gareth Porter studied the case and included that the key “evidence” of an Iranian nuclear weapons program came via the MKO cult and was produced by Israel. 
Porter suggests, “The MEK role in transferring the documents indicates that they originated in Israel, because the MEK had been serving as a client of Israel for several years, including the “laundering” of Israeli intelligence reports by presenting them to the IAEA and the press as coming from the MEK itself.” 
Moreover, in November 2007, National Intelligence Estimate (NIE) of the US reported that Iran had “halted its nuclear weapons program in 2003.”  However, Iran never had a weapons program—at least not one that has been confirmed by U.S. Thus that the unproven MKO-Israeli, nuclear weapons claim has become the source of all deceptive propaganda of the group.
While the MKO leader makes efforts to show off her cult of personality as a secular democratic alternative for Islamic Republic, critics found out the opposite. Holly Dagres of the Huffington Post refers to Rand report to prove dishonest of Maryam Rajavi and her supporters,” Despite denials, its [the MKO’s] conduct tells otherwise as cited by a RAND report: deceptive recruitment, emotional isolation, extreme degrading peer pressure, forced labor, imprisonment, lack of exit options, sexual control, sleep deprivation, and physical abuse.” 
Dagres remarks that the MKO has no public support inside Iran and despite its claims its slogans never reflect the aspirations of the Iranian nation. He writes,” Not only has the Mojahedin-e Khalq lost its support because of its alliance with Saddam during the Iran-Iraq War of the 1980s–an insult to the Iranian people’s nationalism–but also for its position against Iran’s nuclear program, something the average Iranian sees as their legitimate right.” 
Maryam Rajavi and her sponsors must understand that their determination to obstruct nuclear talks and engagement with Iran is not in line with the Iranian people’s longing for independence and security.
