Dear Diary: I have been having an increasingly uncomfortable weekend as leaders as diverse as Abbas, Merkel, Cameron and Netanyahu have announced plans to join a million-strong march in Paris to show solidarity with the murdered cartoonists of Charlie Hebdo. My aides have been whining about the bad optics of my being absent. It's all very well for them --they don't have to miss multiple rounds of golf and expose themselves to potential snipers along the Champs Elysees and the Arc de Triomphe. "When in doubt, retreat. Then run like hell," I always say. And I'm always right.
