To look at most of the photographs of the march in Paris the Sunday after the terror attacks was to see something glorious after the horror that had gone before. More than a million people had gathered to proclaim their defiance in the face of jihadi insistence — enforced in this case by mass murder — that Islamic fundamentalists would determine what could or could not be written, said, or drawn about Islam. And then there were the images of the leaders — Merkel, Hollande, Cameron, and all the rest of a somewhat motley crew (but not Obama) — marching side-by-side, sometimes with arms linked in a gesture of unity. But all was not as it seemed.
