One key sentence in President Barack Obama's press conference at Camp David last week clearly illustrates the gulf between Washington and its allies on the Arabian Peninsula when it comes to Iran.
"We gave [our allies] our best analysis of the enormous needs that Iran has internally and the commitment that Iran has made to its people in terms of shoring up its economy and improving economic growth," said President Obama, when asked about concerns that Iran would use the money from sanctions relief for nefarious aims in the region.
He added that "most of the destabilising activity that Iran engages in is low-tech, low-cost activity".
