muslims do not have any faith in democratic system.they don't trust,if in a democratic system,some one is elected,then he is over powered or killed.main cause of unrest in islamic world is lack of trust and faith amongst them selves.with out any reason they take the shelter of religion.there is no democracy im muslim nations.terrorism is one part to capture power.taliban,al-quaida or any organisation have no deep rooted philosphy.if they capture power,then they will do similar to what happened in afghanistan.you do not offer prayer to GOD with gun in your hand to kill an innocent.look towards iraq,they are killing each other.we only pray to god give them wisdom.no religion preaches killing innocent persons.
