About that non-handshake between Trump and Merkel this week... Yes, it was a snub. It was also astonishingly crude. If you want to convey disapproval of a political leader there are plenty of ways of doing it, all of them better. Trump doesn't seem to know what the art of the diplomatic snub is. Just another thing he doesn't know. To be fair, though, Merkel herself wasn't that phased by it. One could almost hear her thinking: OK, if that's the way you are, then that says it all. So she paused, and in that pause she showed that she was less than eager to shake his hand, too. Who looked like an idiot? Not Merkel.
