The new POTUS has developed foreign and trade policies ideas which clearly go against the consensus formed for decades within the United States government about what to do abroad, and especially in the Middle East. For instance, the US alliance with Saudi Arabia has been – in addition to deep ties with Israel – the cornerstone of US interests – both military and business – in the Middle East.
Considering the promises Trump made during his presidential campaign about foreign policy, this is therefore on geopolitics that Sunni monarchies’ concerns are big. On the Palestinian issue, on the support to “rebels” in Syria and on the treatment of the Islamic world in general, a majority thinks Trump could damage relationship between them and the United States, prompting further developments between Europe, Russia, China on the one hand, and Saudi Arabia, Qatar, UAE on the other hand for example.
However such fears lose much of their importance since Trump repeatedly pledged to cancel the Nuclear Deal with Iran that is both the sole real and the most serious strategic concern for Sunni monarchies. On trade affairs the consensus mostly looks like “business as usual” given that business interests that exist between the US and Sunni monarchies are so big – and profitable – that there would be no sane reason for anyone – even POTUS – to terminate them.
In the end, Sunni monarchies might adapt their foreign policy according to the choices made by Trump but shouldn’t radically alter their global vision of America as a long-term ally and largest business partner.
