I don't think that most thinking people necessarily believe that a so-called "solution" even exists.
As long as Western economic and national security interests are tied to the ME, we will continue to exert our influence in the region, just as Russia and China will. To cease to do so, would open the door for our rivals and competitors on the world stage to gain advantage over us. But, as long as we continue, we will invite the ire and wrath of extremist groups who resent our influence in their homelands.
Until we no longer need the one commodity that the countries of the ME produce... oil... we will continue to incur the wrath of extremists who use terrorism as their only viable weapon against us and other Western powers.
If a "solution" exists, it would involve ending our dependence on their oil so that we can reduce or eliminate our interests in the region.
But even if we completely disassociated ourselves politically, culturally, economically and militarily, we'd find ourselves having to ignore the human rights abuses that would almost certainly continue unabated and likely even escalate in the absence of any Western oversight.
The question then is, could we turn a blind eye to mass human suffering for our own convenience and safety?
I'm not sure we could.
