The world has changed a lot in the past 100 days, with Japan being somewhat brought to its knees by a freak combination of natural and nuclear disasters, and the Arab world being thrown into upheaval. While Japan has managed to control its ongoing nuclear problems (which may or may not have been seriously blown out of proportion by Western media), the Arab world, specifically Libya, is still facing serious issues. The Toronto Star describes the Arab uprising surviving 100 days and still going strong. Libya is in the midst of civil war with Western aerial military intervention, while Yemen, Bahrain and Syria have seen public protests and deaths of civilians.
The US has led the Western aerial intervention (now led by NATO, but with the US still in a leading role) in Libya, despite widespread foreign and local (US) concerns about military action against another Muslim country, and this is strongly a result of Libyan opposition, Arab League and international pressure for supporting the anti-Muamar Gadhafi rebels. What it shows is that for all the talk about US imperialism or conversely, the decline of the US, Europe is still not prepared or not willing to step up. I've never been a strong supporter of the US but this is one instance where it does not deserve the bulk of criticisms for its military role. On the other hand, there have been a slew of voices saying that this is all a sleigh of hand done by the US and Western powers, that instead of having been dragged kicking and screaming, the US actually orchestrated it this way, but for now, I'm going to say it sounds mostly like conspiracy theory.
