"It is shameful for a country which is apparently a superpower that its national security official takes salary from a terrorist cult with a record of killing 17,000 innocent Iranian citizens," Shamkhani said in Tehran on Sunday.
He, meantime, underlined that the US officials have so far used different instruments, including military intervention (Iraqi-imposed war), economic sanctions, attempts to weaken defense power and creation of different political and security crises to stop Iran's progress but all of them in vain.
In relevant remarks last week, Spokesman of Iran's Guardian Council Abbas Ali Kadkhodayee underlined that appointment of John Bolton shows Washington's continued support for the terrorist groups operating against Iran.
Kadkhodayee's remarks came after US President Donald Trump announced plans on Thursday to replace his national security adviser, H.R. McMaster, with John Bolton, the former US ambassador to the UN and a military intervention hawk.
Bolton, as the American sponsor of anti-Iran Mujahedin-e Khalq Organization (MKO) terrorist group, has managed to grab the highest political position in Trump's government, Kadkhodayee wrote on his Telegram channel on Friday.
He wrote that the MKO, the most hated terrorist group among the Iranians, has carried out numerous terrorist attacks against the Iranian civilians and government officials and sided with the former Iraqi dictator, Saddam Hussein, during the eight-year Iraqi-imposed war against Iran in the 1980s.
"Now the question is why Bolton has been assumed to a sensitive position, while he is a stubborn supporter of anti-Iran terrorist group, the MKO," he asked.
Also on Sunday, Hossein Naghavi Hosseini, spokesman for the influential parliamentary committee on national security and foreign policy, told the semi-official ISNA news agency that Bolton’s appointment, as well as that of former CIA chief Mike Pompeo to U.S. Secretary of State, “proves that the final U.S. purpose is overthrowing the Islamic Republic (of Iran).” He added that the U.S. will use MEK to achieve that aim.
