We live in a topsy-turvy world, to say the least. This year’s presidential election brings Donald Trump to the White House (or maybe he will govern from his condo on Fifth Avenue); Alexis Tsipras wins three popular votes in a row in Greece; and Angela Merkel seeks a fourth term. Britons have voted for Brexit but may be changing their minds; the far right is gaining ground everywhere; and oil prices are too low for deep-sea exploration but US shale gas is the new El Dorado.
