Third, the nuclear deal with Iran, despite facing continued scrutiny in Iran and the US, has raised hopes that the country could play an important role in pushing for a political solution in Syria. Not only is Iran’s policy of supplying weapons and fighters to keep Assad in power unpopular at home; the country’s leaders also recognize that fighting the Islamic State in Iraq is a half-measure at best, as long as the group controls vast swaths of Syrian territory.
第三，与伊朗的核协议尽管还面临伊朗和美国的后续审议，但让人感到伊朗可以在政治解决叙利亚问题方面起到重要作用。不仅伊朗为巴沙尔提供武器和兵源以保证他的权力的做法在国内鲜有人支持；伊朗领导人也认识到，只要伊拉克的伊斯兰国控制着叙利亚的大量领土，与该集团的斗争最多只能是权宜之计。
