Tunisia Egypt Libya who's next

Hi, All Watching the news and reading documents about the protesting in these countries and overthrowing governments through political pressure has me questioning who is next?

Other questions arise such as: where did the protests start? Why do other countries such as the UK and USA get involved - although I feel there is always an agenda in any political environment.

Who is next? If it was Saudi Arabia, with the special interest in the family in charge and the links to the US and oil it makes me think about the complications. I still think we are all f*cked and I only ask questions, my view is that we should have a none intervention foreign policy.
