Things might be different if the US and other key players could simultaneously embark on a broad regional stabilization enterprise, but there are too many competing agendas to make this realistic for the foreseeable future. The Sunni-Shia rivalry means that Saudi Arabia and the Gulf countries will concede no meaningful role to Iran.
如果美国和其他重要行动方能共同构建一个广大的地区稳定机构，情况或许会有所不同，但在可以预见的将来，有太多的矛盾日程阻止这一幕成为现实。逊尼派-什叶派对立意味着沙特阿拉伯和海湾国家不会对伊朗做出任何有意义的让步。西方也不会承认伊朗在任何多边进程中的核心地位，担心因此失去在伊朗核计划谈判中的筹码。
