Henry Kissinger

In the late 1960s and early 1970s, under the presidencies of Richard Nixon and Gerald Ford, Kissinger was a giant and charismatic figure in global diplomacy.

The former US secretary of state, who has died at the age of 100, was one of the most controversial and prominent figures in US foreign policy.

Henry Kissinger warned that President Obama's reputation will largely be determined by what the end result is over Syria.
