Waiting, wanting

How many times we wished to be just observers in this hell driven world? I always remember the question once asked: Can we all get along?
Watching the recent events that are happening in the Middle East, I doubt that we could reach a state that keeps peace as a must.
Maybe the reasons are in the far past, when people were divided in between the sons of the slave and the sons of the promise. Come on, they are family, they are related, no one can see that?
Or is it just because they are relatives, is that why they have to fight?
