To some degree, this hope is reinforced by Iran’s perception of US President Barack Obama as a motivated partner in the nuclear talks. After all, a long-term agreement would be both a singular foreign-policy achievement for Obama and a boon to his efforts to disentangle the US from the Middle East.
从某种程度上说，这一希望因为伊朗将美国总统奥巴马视为核谈判中有积极性的伙伴而加强了。毕竟对奥巴马来说，与伊朗的长期协议不但是突出的外交成就，也有利于他让美国摆脱中东。
