Is the USA behind the unrest in the Middle East & Africa?

Almost at the same time Middle Easterners & North Africans are revolting against their leaders & the dictatorships they control. Have these actions been championed by the USA and NATO? Have we taken the war to the back door instead of the front line? Is our support for the rebels more than what we see? When the dust settles will we see more democracies in the region and more stability? As the people gain more human rights and prosperity will oil prices finally be more under control by free governments there and abroad? I think the answer to all these questions is yes! What is your opinion?
