Does the option for policy in Iraq recommended by Stratfor in recent analysis provide the practical bridge for realistic policies considering geo-politcal realities, allowing this to become a less-military intervention?

I think the following post from jcustis, deep in the Kilcullen thread, succinctly puts the fundamental issues of (non)alignment between the parties in the Iraqi "government."
I think we've done all we can to advance this idea marct...the walls we are banging our head against is the fact the the various parties aren't buying what we are selling. For the Kurds, the future of Iraq remains semi-autonomous rule in the north. For the Shi'a, the future is an ascendency of power aligned with Sadr in Baghdad, and Sistani in the south, with a bit of help from Iran where necessary. For the Sunni of Al Anbar, they probably see their best future as an Anbar operating in a semi-autonomous realm as well.
I outlined the Stratfor recommendation in my post in the "thoughts on a surge" thread, but it didn't seem to stick. Maybe poor timing, maybe my post sucked more than I thought. The meat of it re-stated here, summarizing the approach:

----------
[I ponder whether the original US objectives in Iraq are] now feasible, and if so, what actions are necessary to gain and maintain the large surge needed to establish the presence that enables that security, and whether the resultant risks elsewhere in the GWOT and global environment are worth taking. Can we / should we go big enough, long enough?

Still getting my head around the Stratfor Special Report, U.S. Options in Iraq, I recently read. I read a hard copy via a subscribed compadre, I don't know if it is available on the web via their free trial, it was one of their premuim reports.

If I can do their analysis justice in this short summary, their assessment -- which is about the only one that has rocked me off my "we must win" position -- is as follows:
  • We don't have the forces to sustain a strategically significant surge.
  • We can't just leave and let the place implode (as Iran wins too much)
  • We can't just stay the course (not winning, slippery slope to losing).
  • We don't have any real allies left on the ground. (that make a difference)
  • Iran, not just Iraq and not really anyone else, is the key. And their influence (but not control) over Iraqi Shia.
  • Iraqi forces do not need training, they need loyalty and alignment of interests. We can't provide that.

The fallback objective becomes CONTAIN Iranian power and PREVENT their regional hegemony, with the caveat that since we've screwed up as much as we have so far, they're going to gain a little status/power. Just stop them from gaining too much. If we shoot the moon in Iraq, we might lose and let Iran win big in the region.

The tactics they propose:
  • Withdraw U.S. forces to containment positions:
  • Bulk in southern Iraq, in Shiite territory (watching them, esp for Iran influence) and buffering Shiite / Iran influence from Saudi Arabia.
  • Smaller force w/ Kurds (they have more organic capability, and aren't main effort)
  • Let the Sunnis have Al Anbar. Influence through diplomacy and local partners, esp. Saudia Arabia. Dicey, but less so than some of the other diplomatic miracles we're counting on.
  • Let the Iraqis solve their own problems, in a contained, mitigated environment. Maybe still ugly, but lightest shade of gray feasible.
They suggest we should not maintain our myriad strongpoints anywhere but in the relative safety of our buffer zones, but note there will be political pressure to do so far more than makes sense. Compromise suggested is BIAP only.

So...at first it pissed me off as defeatist. But the more I mull it over, the more I like it. What do you think?
