Iran is faultless, and Japan government should not accompanies Mr. Trump's sanctioning Iran. Iran officials participated in a long negotiation with 5+1 (five European government plus to USA government) under supervision and management of United Nation Organization, in the historical JCPOA agreement, about two years. The subject of the negotiation was the nuclear energy technology of Iran. White House claimed, Iran is tending to produce nuclear weapon and Iran responded, we are a humanity and peaceful nation and have never made a decision to produce a horrible massacre weapon such the atomic bomb. We use our technology in a peaceful way in the our power plants or for medical purposes. White House denied the declarations of Iran and persisted on its accusation. Eventually the international negotiation was established and continued for about two years. In this period of time Iran government allowed the Atomic Energy Agency of UN to visit the nuclear sites of Iran and does a comprehensive research and investigation about atomic activities of Iran. After many researches that the agency did, it finally confirmed which Iran's nuclear activities are peaceful wholly and there is not any sign of production nuclear bomb equipment and devices in Iran. However, after the two years negotiation and reports of United Nation Atomic Agency 5+1 had to sign an international agreement ( JACPOA) that Iran is rightful to continue its nuclear activities but with less amount of uranium and centrifuges. Instead, White House and European governments (5+1) were obligated to remove the economic sanction versus Iran. One of the signers of the international agreement was the president of America, Mr. Obama, as the representative of USA government. What happened later? Mr. Trump, was elected as the new president of the United State. After a while, he claimed the conventional defensive medium range missiles of Iran should be included the agreement! He didn't consider that the international agreement that was signed by government of America was about nuclear activities of Iran and the conventional defensive missiles that are made by every country for security of the land are irrelevant to the signed international agreement! Iran protested to the unjustifiable claim of him, and president Trump told, he will cancel the agreement because it is not perfect!! He did the same and after the months, he proclaimed he has gone out of the international agreement that Obama has signed it because of his stupidity! European governments advised him to stay on the promise of USA government against United Nation Organization and doesn't leave the legal agreement, but he didn't agree! He proclaimed, the global economic sanction is renewed versus Iran and neither governments nor corporations of other countries should not have any business deal with Iran! (just opposite to the international agreement, that the USA government signed it earlier!) So , which agreement would be reliable after the firm international agreement that Mr. Trump canceled it based on his personal idea?! Which country will follow this idea that is opposite to the laws and logic of United Nation Organization's official bound?! I believe, each government that participate in this breakage of covenant puts its reputation and credibility in a risk of accusation of irrationality . This is because I recommend Japanese politicians not to accompany president Mr. Trump in his lawlessly decision, though there is not a notable commercial relation between Iran and Japan.
