People won't throw out their 'old ways' to be replaced by western democracies, they will take what they like about our systems and amend them to fit their own culture, history and socio-economic environment.

Problem is that is what caused things like the protests against mubarak and gadaffi in the first place. You can't just take bits of things that suit you about one system, or adopt it in a piecemeal fashion, does not simply work that way. There is a reason the USA became the worlds power from 1776 after throwing off the yoke of the british, obviously the young unions economic and legal and political systems were created in such a way that they simply worked, as what was achieved was unprecedented in history, ex colony becoming a superpower. I'd also wager a part of it was the legacy of parliamentary democracy introduced by the british and good old anglo saxon work ethic in the mix. Arabs are inherently tribal, so democracy can't work as in the west, and the Chinese need a big leader or emperor and the whole confucian system. It will be back to mud huts or the rice fields soon enough, its a ticking time bomb in those places.
