Meanwhile, America’s relationship with its traditional Arab allies – the region’s conservative Sunni regimes – is faltering, owing largely to US President Barack Obama’s failure to respond effectively in the aftermath of the Arab Spring uprisings. Obama’s offers of security guarantees and “nuclear umbrellas” have not been able to restore their trust.
与此同时，美国与其传统阿拉伯盟友——中东地区保守的逊尼派政权——的关系正在趋于平淡，这主要是因为美国总统奥巴马没有在阿拉伯之春动乱后有效响应。奥巴马所提供的安全保障和“核保护伞”没能重塑它们的信任。（毕竟，这些安全保障只是间接的。）
