Lovely short series examining the historical role of diplomats in representing British interests. Since it’s presented by a former British Ambassador to the US, Sir Christopher Meyer, it takes a fairly predictable “we’ve got a difficult job y’know” route, but still manages an interesting investigation of past incidents and asks some tough questions.

Most of which don’t have clear answers. Bottom line: you have to deal with the world as it is, not how you would like it to be.
