Well simple is that isreal is the worst enemy of Muslims . You know too . if you see the passport of Pakistan you will see that the PAss port is valid for all countries expect Israel . however we will see a war soon . some people said that USA is also involed too but i dont know . they say that israel like countries (the enemies of Muslims ) wants to create fight among muslims . so they die fighting between . we see some fights between sunni and shia . the reason behind the fight is too obvious . however some peoples misguide the sunni about shia and shia about sunni . here is a screenshot .i found this on google . on the rigt side is shia and on the left sid is sunni and you see two hands coming behind both of them .
