Up untill the time of the CIA "Operation TP Ajax" Iran was more democratic than the United Snakes. That takes care of your question of "possible". Not merely possibe - but fact.<quoted text>democracy in the middeast/persia??,...hmmm is it possible? or preferable?
"Preferable" depends upon how the people of the Middle-East view the actions of the United Snakes. American regimes have been displaying Fascist tendencies, yet call themselves "domocratic". The best example is the United Snakes' illegal invasion of Irak on a pure lie. So do the people of the Middle-East see the United Snakes as an example of Democratic principles? There lies the answer to your question of "preferable".
