There's an article in today's Guardian about how Russians are responding the terror threats with a mixture of stoicism and dark humour.
From the article:
At a cocktail party held to welcome the new British ambassador, I met a Russian media critic, known for his toadyish apologies for the Kremlin. He sweated a bit from the forehead - more from the whisky than the heat - as he explained how Russia would beat terrorists, a wry grin underscoring that he was only partly joking.
"We will shock them with our incompetence and our disregard for human life", he said. "And eventually they will just give up, seeing the attacks are pointless and change nothing."
