Answer by Ken Larson:
We should not expect your objective will be achieved considering the events of the last two decades in the Middle East.
From the Gulf War to the invasion of Iraq, from Arab Spring through Syria, it is apparent the region will be in chaos with power vacuums and power assumptions for years, drive by religious radicalism and a tribal mentality.
The U.S and Western powers as well as Russia must recognize the above facts and leave the Middle East. Their very presence has been driven by their Military Industrial Complexes with money or geopolitical proxy as drivers – not democratic ideals or even communist ideals.
The Arab/Israeli issue must be resolved with international negotiation. All wars eventually result in negotiated settlements. Avoiding them by negotiation in the first place is the most effective war weapon and by far the least costly in materials, debt and lives.
Your assumption is entirely impossible in the cultural environment of the Middle East. We have not realized that military victory is dead. It will take many more deaths to bring that reality home. The great powers must decide how many more deaths they wish to cause or donate.
