IRNA � As one of the major multilateral diplomatic achievements acclaimed by different sides, two years passes of the world's affirming the Joint Comprehensive Plan of Action.

Being the fruit of a series of difficult and lengthy negotiations between Iran, world�s major powers and the European Union (P5+1+EU) over Tehran�s nuclear activities, the JCPOA was finally signed by all sides on July 14, 2015 in Vienna.

During the past two years and within the period of the historic deal implementation, the JCPOA has been facing some ups and downs mostly by one the sides of the deal which happens to be the US making up excuses and trying to put the deal under question.

Continuing its principled policy to build confidence, Iran has implemented the JCPOA precisely throughout the past 24 months and this can be proved by the International Atomic Energy Agency�s (IAEA) several reports approving the full implementation of the JCPOA contents by Tehran.

The European Union has always stressed the full implementation of the JCPOA by all sides including the US.

�We will guarantee that interaction with Iran will continue and all sections of the JCPOA including those pertaining to lifting sanctions will be fully implemented by the involved parties,� said the High Representative of the European Union for Foreign Affairs and Security Policy Federica Mogherini in a press conference with Russian Foreign Minister Sergey Lavrov in Brussels on July 11.

Noting that the European Union is united in defending the landmark nuclear deal, she said that Europe has security interests in full implementation of the deal and interaction with Iran. Not to mention that economic interests are also conceivable.

�We know that the US is reviewing its policies and we respect it, but JCPOA does not belong to a single country; rather it belongs to the international community and has been endorsed by the UN Security Council,� Mogherini stressed adding, 'we have the responsibility to make sure that this continues to be implemented.'

Other involved parties in the JCPOA have also expressed their support of the historic deal like China and Russia.

China has called the JCPOA a historic turning point and has urged the full implementation of it stressing that this achievement can be an inspiring model to solve other (world) issues through diplomacy.

Russia has also stressed that the JCPOA�s capability of implementation and its acceptance as an international agreement by all involved parties have been proved in the past 24 months.

In between, the US new administration, still confused and shaky about the JCPOA, has announced that at the moment they are so-called �reviewing� their policies toward Iran and they will adhere to JCPOA until adopting the new policy.

The US President Donald Trump who had claimed in his presidential campaigns that the JCPOA was the worst deal ever in the history, has been stepping back of making any further criticism about the landmark nuclear deal as an indication that he has admitted to it as an important diplomatic fact.

Meanwhile a recent ratification of a new plan on imposing sanctions on Iran in the US Congress is still in a halo of ambiguity due to the concern toward putting the JCPOA in danger and even after ratification and its signing by Trump it will continue facing vagueness.

The US Senator Bernie Sanders is among the severe critics of the new plan of imposing sanctions on Iran and has stressed that the plan is risky and endangers the JCPOA.

The important point which has to be seriously taken into account is that based on the world officials including the Islamic Republic of Iran and the EU�s officials, the JCPOA does not belong to one country and one country alone; on the contrary, it belongs to the international community and is a multilateral and universal achievement which has also been approved by the UN Security Council.

The Iranian Foreign Minister Mohammad Javad Zarif, upon his arrival in New York on July 14 (Thursday afternoon in New York local time), stressed that the JCPOA is a universal agreement which has made it clear that �the followers of the policy of pressure have finally realized its inefficiency; therefore, the US should also reconsider its approach towards the agreement.�

Two years after the historic nuclear deal was born, the Islamic Republic of Iran�s good will has been proved internationally and it is the US� turn now to avoid breaching the JCPOA and adhere to its commitments which helps this international document last long.
