Amid the epic remobilisation of millions of Egyptians against their government last Sunday, there was one of those little signals that elude precise interpretation. As vast crowds reassembled in Tahrir Square to demand the departure of Mohamed Morsi, Egypt’s elected Islamist president, with all the venom they deployed to bring down Hosni Mubarak’s army-backed dictatorship in 2011, something remarkable happened. Army helicopters hovered over the square, dropping Egyptian flags, to wild cheers and celebratory fireworks from the ostensibly liberal and leftist crowd below. The army claimed it was stimulating patriotism at a time of national crisis. It looked as though it was flirting with the masses, revealing a tantalising bit of military ankle.
