The title implies the middle east was ever not torn apart. A quick glance through a history book shows it has always had more than its fair share of sectarian violence. It is resource starved and a major crossroads, why should we expect anything else without major effort to fix it?
And you are also implying that 'a major effort to fix it' would make us expect something new.
Both things are wrong. The US has been military active in middle east since almost 40 years (longer with the CIA). The US has major military bases all over the place, has invaded, bombed and fought wars with many countries, has supported one group or another in a civil conflict in all of them.
All of this was basically done because of the Carter Doctrine, the ME is a vital strategic area and its stability is very important to keep the oil flowing. How does this not qualify as a major effort?
What of all of this suggest to you that the US, or even a bigger international community could 'fix it' with a 'major effort'?
