New Domino Theory?

So with Tunisia and Egypt overthrowing their leaders protesting for reform we have Yemen and Iran having protests for reform. Proof that America does not need to invade countries to give people freedoms they desire. So in the future world history books do we call this a new domino theory where one leader is overthrown and next countries over overthrows their leaders. Perhaps to use the football term, Wave of Reform or perhaps Tidal Wave of Change. Just a thought.
