War On Terror After Osama

What will be the world after Osama? Is it the end of war on terror or this will turn a new position?  This is the question now a days discused on all the forums.  According to my ideas this will not be end of war on terror.  It will take a new turn because only the leader is dead but the other leaders of second line are alive and they are well know for the world.  War on terror is more powerful and more dangerous than that of cold war against Russia.  War on terror is the war against ghosts. Enemy is not in the frame and we do not know actually who is our enemy; some times they are our friends, some times they are working with us. We do not know who they are; this is alarming situation and realy this is enhancing our blood pressure.  We are fighting against whom we are not sure realy who they are we can not nominate them only, 10 or 20 peoples are nominated, but where is their army?
