I think death of Osama will not make world safe because his followers will not sit peacefully but may be its possible that they take revange of osamas's death to innocent people and spread more terror than before. And may be this will make another osama alive.
You are right hinal. In my think it is not possible to stop terrorism.
Maybe you r right in your side. But in my think no body can remove this virus permanently.
Thanks & Regards
