Killing Osama bin Laden (or rather, signing off on the ongoing military operation that killed him) might have given Barack Obama a great electoral pitch, but what exactly did it accomplish for the security of the United States and its interests? Al-Qaeda is back – big time. As a man who knew something about indefatigable terrorist organisations once said, “They haven’t gone away, you know.” As we learn more of the horrific details of the Algerian hostage crisis, it becomes clear that the old outfit is getting on just fine without its nominal head, scoring a hit of quite spectacular global proportions, which threatened nationals from as large a number of countries as would ever be likely to gather in one place of employment. I wonder how much attention this incident – or for that matter, the murder last year of an American ambassador in Libya by an organised al-Qaeda attack – will be given in Mr Obama’s second inaugural address tomorrow?
