Скачать или смотреть Donald Trump's instinctive approach to policing the world

Donald Trump could not have been clearer on the 2016 election campaign trail – he would rip up the norms of American foreign policy if he made it to the Oval Office. 

The country had suffered too much for too long over its interventions in the Middle East after the September 11 attacks, he argued. 

Old allies had been free-riding on America’s willingness to pay up for the West’s defences, Mr Trump said, dubbing the North Atlantic Treaty Organisation [Nato] “obsolete”. 

And, in a stance that contradicted starkly with the other Republicans running for their party’s nomination, surely it was time to mend the relationship with Russia rather than taking the country on? 

Since entering the White House, Mr Trump’s record on foreign policy has been uneven. He has followed through on promises to trigger a change in the North Korean dynamic and pull out the Iran nuclear deal. 

Is Mr Trump hammering away at the cracks in the post-World War Two world order so carefully constructed by America and its allies? Or is his lack of ideological baggage helping unlock foreign policy conundrums that have remained unsolved for years?
