I doubt that the Obama administration understands this or appreciates its significance, but: what it is doing by facilitating Iran is simply removing longstanding US support of the Sunni side in the long-simmering Shia-Sunni war. Iran is gathering the Muslim world’s Shia into one fold under one shepherd. From the standpoint 0f the world’s long-abused Shia, this is great. This, in itself, is of no direct relevance to the US. Hence US neutrality in it is, in principle, a wise thing.
Whether it is so in any given instance, is another matter.
