Oh cool, just what I always wanted, another thread dedicated to Israel and palestinian conflict.
To those members who wish to "take arms against the kufar in order to prevent massacres", here's a new method. Why not help preserve life via donating through charities, sponsoring orphans, looking after the elderly, donating money to palestine etc. This method involves no killing, no haram and it is perfectly legal.
This is the real world, not an action movie, you can't just go around killing people and hoping it will solve all your problems. Besides, do you honestly think one extra soldier placed on the battlefield on either side of this conflict will change the outcome? This is not how wars or any conflicts of any kind are stopped. Think it through logically : you kill them, they kill you and sooner or later everyone dies.
