There is a news picture of Foreign Minister Julie Bishop that sticks in my mind.

Bishop, lithe, agile (that word again!) jogs, smiling and confident, with her sweaty, be-suited Chinese bodyguard in his polished leather shoes, toiling behind, on an official visit to China.

There’s another one too, Bishop, fetchingly head-scarfed –not quite hijab-ed, her trademark blonde fringe peeping from under the folds of fabric- during her official visit to Teheran.
