Should we go one step further and do like we did in the Iran/Iraq War and support both sides or in this situation....all of the sides....and let them get on with killing each other? Or is picking the "friendliest" of the many factions and supporting them the right answer....assuming we pick the ones that shall prevail and become the "Winners"?
That part of the World have been fighting since time immemorial so why should we expect anything else from them? If we play the right cards we might find ourselves allied with Regimes/Groups/Countries that will be somewhat stable and aligned with our needs and goals for the Region.
We would not need to commit ground combat forces to the region beyond those needed to safeguard the delivery points and training facilities.
