INTRODUCTION: THE HOT SUMMER OF 2015 MARKED AN IMPORTANT TURNING POINT IN INTERNATIONAL RELATIONS, ESPECIALLY BETWEEN COUNTRIES THAT UNTIL THEN HAD DECIDED TO REPLACE THE WEAPON OF DIPLOMACY AND DIALOGUE WITH THE WEAPON OF CONFRONTATION AND CONFLICT. IN 2015 A PART OF THE INTERNATIONAL COMMUNITY DECIDED TO PUT AN END TO THE PROBLEM OF IRAN'S NUCLEAR PROGRAM WITH THE SO-CALLED VIENNA Agreement, BY WHICH THE 5+1 (US, UK, FRANCE, RUSSIA, CHINA AND GERMANY) PUT BLACK ON WHITE, AND SIGNED A HISTORIC LEGAL TEXT WITH THE ISLAMIC REPUBLIC OF IRAN. THAT Agreement WOULD PUT AN END, GRADUALLY, TO THE SANCTIONS AGAINST THE ISLAMIC REPUBLIC, ECONOMIC RESTRICTIONS DUE TO THE NUCLEAR PROGRAM OF THE AYATOLLAH, ACCUSED OF TRYING TO DESIGN A NUCLEAR WEAPON. ON THE OTHER HAND, THE ISLAMIC REPUBLIC THROUGH HIS SIGNATURE AND HIS CONSENT PROMISED TO DRASTICALLY DOWNSIZE ITS ATOMIC PROJECT, BUT RESTATED THAT THE PROJECT HAD AND HAS ONLY CIVILIAN PURPOSES. WITHOUT WANTING TO REDUCE THE ROLE OF THE OTHER ACTORS AND THE OTHER CONTRACTING PARTIES, IN THE VIENNA Agreement OF 2015, THE MULTILATERAL INTERNATIONAL TREATY THEN RATIFIED BY THEIR RESPECTIVE PARLIAMENTS, CONFIRMING WHAT IS THE CLASSIC PROCESS FOR THE SIGNING OF INTERNATIONAL TREATIES1, THE MAIN ROLES HAS BEEN OCCUPIED BY THE US GOVERNMENT AND THE IRANIAN GOVERNMENT. FROM THE DAY IN WHICH THE VIENNA Agreement ENTRY INTO FORCE, THE TWO MAIN PARTIES HAVE ACCUSED EACH OTHER REPEATEDLY OF HAVING BETRAYED THE PACT, BUT THAT HAS NEVER HAD THE EFFECT OF DAMAGING THE MAIN POINTS OF THIS Agreement: THOUGH THE CHANGE OF GOVERNMENT IN WASHINGTON AND THE RISE TO POWER OF THE CHARISMATIC REPUBLICAN LEADER, DONALD TRUMP, WITH HIS STATEMENTS CONTRARY TO ANY KIND OF Agreement WITH THE IRANIANS, WE MAY HAVE SEVERAL PROBLEMS FOR THE IMPLEMENTATION OF THE JOINT COMPREHENSIVE PLAN OF ACTION (JCPOA), THE OFFICIAL NAME OF THE VIENNA Agreement OF JULY 20152.
