If you see the sequence of events, the fundamental of all the issues are interference..Rather than focusing on developing your own country, these nations which are in conflict zone try to influence and interfere in other nations...Study the events in middle east and even Kashmir too...
Why do not you see any conflict in any other Islamic nations? See for example countries like Bangladesh, Indonesia, Malaysia which are doing very well economically and proud muslim nations...they do not have any conflict...But the entire middle east is messed up due to ego of each Islamic nations starting with Arabs, Iran and then late entrant to the game in Turley and Pakistan...It is just getting messier day by day....
