You could say the west is manipulating, yes, but there are other things happening too. The global technology revolution has helped - the Arab Spring for example seems to have been a social media led uprising - dictators falling to the masses in poorer countries. But I think the US and UK have played a big part in 'allowing' these revolutions to occur. They want to democratise the world of course but only when it's safe and right to do so. They wouldn't think of putting pressure on the Middle East oil states for example - sheikh land- where feudal families rule with an iron fist. I wonder why they 'allow' this kind of dictatorship to exist, yet want to get rid of others?
In Egypt right now you have a very strange situation. A democratically elected president, Morsi, has fallen because of a military coup d'etat - and yet the west is silent. Why? Because Morsi was part of the muslim brotherhood and we all know what that means? So the US and UK are happy, which is plain hypocrisy. They'll spin and bluff their way around this one but the consequences for the Arab world could be catastrophic.
Egypt needs a strong coalition now, backed up by the US sponsored military machine or chaos could ensue.
Next is Syria, a mess. Basically the west is tolerating the actions of a dictator because Russia is stil a big player over there, with China sort of sitting this one out. The UN is toothless. At the moment it looks as if assad will get his way but he'll have to reform or face severe sanctions and more unrest. This to and fro war could go on for a generation. We need Russia to seriously talk to Assad and bring on board the US and UN.
