The problem I see, is that if this stops and the hatred / misrtrust remains, it is only a matter of time before it starts again. perhaps they DO need to fight it out, and yes that means 1000s die on each side, but that area seems a powder keg that keeps going off.
Peace perhaps need to be a result of the middle eastern countries and esp those that border Isreal / Gaza / Westbank finding a solution, It hardly helps that the west removed gadaffi from Libya and left a mess in it's wake. Perhaps the middle east is simple better off telling the US especially to sort its own issues out at home before lecturing others.
It is not as if the USA is currently without lots of seruous issues.
