US President Donald Trump commemorated his first 100 days in office at the weekend.  Continuing a frenzied first three months of foreign policy, the president this week has multiple meetings with key world leaders, including Palestinian President Mahmoud Abbas on Wednesday and Australian Prime Minister Malcolm Turnbull on Thursday.

100 days into office, the nature of Trump’s foreign policy remains largely undefined. His period in office so far has been much clearer for his reversing of previous campaign rhetoric and pledges, than fulfilling them.

Trump promised “a new foreign policy direction” in what was seen, in some quarters, as perhaps the biggest potential shake-up since 1945.
