Agreement00

Writing the nuclear agreement is definitely required to apply the legal knowledge. But the White House American team does not have sufficient knowledge to set up a political agreement based on the principles of international law. Wendy Sherman is for instance unable to negotiate according to international law. Therefore, the US will attempt to negotiate on less important or even solved issues in new round of nuclear negotiations. And this is wasting time. Thus, the initiative of the negotiations should be taken by Iranian negotiators.
Hence it is required to identify some points: 
First, the discourse and literature of nationalism is not able to attract global support for any country. So it is necessary for Iran to be relied on the discourses of international law and Islam to attract the world supports. 
Second, the sanctions matter is one of simple but controversial node of nuclear debates. The recommended solution by international law is to referring to the principle of reciprocity. Reciprocity is an accepted rule and a jus cogens in international law and treaties. And the rule has been accepted at Switzerland statement with prerequisites of verification of the IAEA. Considering that any exception to the rule is valid when is announced expressly, it should be remarked that the principle of reciprocity at Switzerland statement has not been limited to anything but verification of the IAEA.
