Kerry says nuclear deal with Iran possible 'If God wills”

The US Secretary of State John Kerry said nuclear deal with Iran possible 'If God wills”.

According to Laura Rozen, a reporter for Al-Monitor, Kerry “reportedly gave a short and surprising answer when asked if an agreement would be reached by the self-imposed Tuesday deadline.”

On her twitter page which is followed by more than 52,000 people, she said that “Kerry referred to 'Allah' in his answer.”

“Not only did the chief US negotiator at the Iran nuclear talks make reference to Allah; he supposedly did it by speaking Arabic,” she twitted.

“The Arabic term Kerry is said to have used”, - insallah - translates as ‘God willing’ or ‘If Allah wills it’”.

Kerry made the remark in answer to a question posed to him about the future of nuclear talks with Iran when he was shopping for chocolates.
