Many people do not understand that this "Arab spring" goes against the best interests of Arabs. In many of these places, say for example Egypt, for 40 years Mubarak brutally oppressed his own people with Euro-American assistance. These self-proclaimed defenders of freedom knowingly looked the other way while people were arrested and tortured for decades. And now, when these dictators like Mubarak were old and feeble[Mubarak was 84] and was expected to pass away relatively soon and change would have naturally come with people that he had oppressed being able to come out again, this happens.
The people were understandably fed up with their governments, no-one likes to live under such oppressive conditions. And this resentment gets used to instigate - again with US/Euro(NATO) backing [the same folks who supported dictators against the wishes of these people for forty decades], new rulers get installed that are again US puppets. Look at Egypt, Libya, Tunisia. They all have oppressive regimes, Libya has racist terrorists being installed at their leadership - even during the civil war they were killing black-skinned Muslim countrymen in Bengazi. Egypt has a military regime that cracks down on opposition.
The US/NATO role was deplorable and HIGHLY condemnable, supporting these dictators till they were old, and just when they were close to being naturally replaced with successors coming up from within the system, they pull another stunt like this. Their meddling all around the world causes immense tragedies.
And being a Pakistani, we can personally attest to this. We had a military dictator - Musharraf. He did some terrible things, picked random people off the streets and handed them to the US, when the US needed to show they were filling Guantanamo bay with terrorists and hence making progress in the War on Terror. When families and children of these "missing people" protested, he had the police brutally assault and crack down on them. The people were sick of Musharraf, and that popular resentment was used to install an even worse regime. The US got Musharraf to "forgive" tens of billions of dollars of corruption under this infamous law he passed, which allowed these corrupt politicians to return and have a second go at it.
The current president, Zardari, had dozens of cases ongoing against him in numerous international courts. And after years of expensive trials that cost the public millions of dollars, the heat was finally on. Zardari, in a desperate attempt to abscond the summons the Swiss court had ordered for him, had his lawyer plead that Zardari was mentally unfit, and hence could not come to court. The US paved the way for his return, and he has been more malleable and compliant than any ruler we've ever had. He is massively unpopular but that doesn't matter, he got elected in an "election" in which half the votes were fictitious, facilitated by Uncle Sam who claims to be out there waging so many wars and killing millions of civilians in Iraq and Afghanistan in order to make the world "safe for democracy". So - we've personally seen how hazardous the puppet regimes they install can be, because we're living under one.
I hope our Arab bretherin manage to hold their own, and prevent the US from installing puppets all over again, which may then rule them for another 40 years. Uncle Sam is *not* invading oil-rich Libya, and strategically-important Egypt and Syria, for the benefit of their masses. The masses are understandably frustrated, and they can be manipulated into reacting in higly predictable ways.
