Foreign policy, development, and humanitarian aid have had little coverage in the US presidential campaign. However, the issues will still be in the in-tray of Donald J. Trump come January. Here are some of the most pressing:

Syria, Iraq and Yemen

Trump’s statements on the Middle East have been a mix of isolationism and promises to crush so-called Islamic State, making it unclear what he intends to do.

The president-elect has argued that deeper involvement in the Syrian war would cause “World War Three” and bring the US into direct conflict with Assad allies Iran and Russia. “The first thing we have to do is get rid of [IS] before we start thinking about Syria,” Trump has however argued. What that means for Syria and Iraq, where the battle against IS in Mosul is ongoing, is far from clear, as the next president has said his plans to fight the group are secret. Statements on his website make promises to work with Arab allies and friends in the Middle East to defeat the group and “pursue aggressive joint and coalition military operations to crush and destroy [it]”.
