Donald Trump met Henry Kissinger, the former secretary of state and long-time foreign policy guru on Wednesday. Mr Kissinger is the latest in a string of policy experts sought out by Mr Trump as he looks to reassure the Republican establishment that he is not, as Hillary Clinton has described him, a "loose cannon". Mr Trump's "America First" foreign policy aligns in part with Mr Kissinger's realist approach, with both men emphasising US self-interest in dealings with other countries.
