MNA � An Iranian lawmaker said that US President�s decision to fire John Bolton was a testament to the defeat of extremist policies and also for the regime in Tel Aviv.

�This change reveals the failure of Trump�s extremist policies against the Islamic Republic and made it clear that pressures, extremist measures and propaganda bear no result,� Alaeddin Boroujerdi, a member of Parliament National Security and Foreign Policy Committee told ISNA on Sunday.

�From the other side, John Bolton was an agent of the Israeli regime, so his ouster was a failure for the Zionist regime and its anti-Iranian policies,� added the lawmaker.

�Bolton�s ouster doesn�t mean that any change is going to happen in US� policies towards the Islamic Republic. Of course, as long as Trump doesn�t return to JCPOA and remove sanctions, we will have no positive view about America.�

On Tuesday, US President Donald Trump announced that he had fired his national security advisor, citing strong disagreements over several foreign policy issues.

A source familiar with the matter told NBC News that Trump�s decision followed Bolton�s disagreement over easing sanctions on Tehran. Tump's idea, however, did not sit well with former National Security Adviser John Bolton during a Monday discussion concerning Iran in the Oval Office between the two. Bolton told Trump that he strongly disagreed with the idea of easing pressure on Tehran, NBC News reported, citing a source familiar with the matter.
