It's not surprising. Three spontaneous riots? I've been sold lies before but you'd have to be completely hapless to buy this one. The cover-up is undoubtedly an effort motivated by timing (re-election). That said, it won't play much of a role, IMO.
What this does show is we need to recontour our international presence and remove embassies from countries that aren't strong allies. We spend monetary aid, military and diplomatic resources in countries where extreme fundamentalists will hate and try to injure people working there and where the aid gets siphoned off by corrupt despots masquerading as free governments. If the entire ordeal with Iraq and Saddam Hussein taught us anything over the past 60 years, it's that we have no business nation-building and policing the world. We just fuck it up in the end.
I'm not one to advocate government spending, but if we're going to spend money and efforts, let's at least do it domestically. We have shit to build here and a bordering country quickly accelerating toward chaos and paramilitary civil war.
