2021年，美国和伊朗相继完成政府权力更迭。莱希政府上台后，实施“使美国制裁无效”的应对伊核问题新方略：调整伊核谈判在伊朗外交政策中的地位，大幅提高本国的核能力，降低与国际原子能机构合作的水平，积极开展“周边外交”和“经济外交”，以削弱美国经济制裁的影响和应对地区竞争的挑战，同时为重启维也纳恢复伊核协议履约谈判做足准备。“莱希时代”的维也纳核谈判复杂且久拖不决，除美伊国内政治、地缘政治博弈等长期存在的干扰因素外，乌克兰危机是复杂的新变量。2022年是伊核问题决定性的一年，恢复伊核协议的前景存在达成新协议和谈判破裂两种可能性。
The year 2021 witnessed the successive changes of both governments in Iran and the U.S. After taking power，the Raisi administration implemented a new strategy called “Nullifying U.S sanctions” to deal with the issue. Iran adjusted the status of Vienna Negotiation in its foreign policies，strengthening its nuclear ability greatly，reducing its cooperation level with IAEA，actively engaging so called “Peripheral Diplomacy” and “Economic Diplomacy” to impair the Impact of U.S. sanctions and meet the challenges in regional competition，as well as to get fully prepared for the restart of Vienna Negotiation. In addition to the long-standing interference factors like domestic politics in both Iran and the U.S. and geopolitical games，the Ukraine Crisis is a new complicated variable. The year 2022 is decisive for the negotiation. There are two prospects for reviving the deal，a new agreement may be dealt or else the negotiation may be broken.
