George Friedman at Stratfor with an interesting laying-out of scenarios now that the Saudis (evidently, as apart of a coalition) have sent forces across the causeway to Bahrain, to bolster the Sunni monarchy against the current uprising, which stems in part from discontent among the Shii-majority population.
As the report makes clear, the potential implications for Iraq are significant. Add to that this disturbing comment:
If Iran simply does nothing, then the wave that has been moving in its favor might be stopped and reversed. They could lose a historic opportunity. At the same time, the door remains open in Iraq, and that is the main prize here. They might simply accept the reversal and pursue their main line. But even there things are murky. There are rumors in Washington that U.S. President Barack Obama has decided to slow down, halt or even reverse the withdrawal from Iraq. Rumors are merely rumors, but these make sense. Completing the withdrawal now would tilt the balance in Iraq to Iran, a strategic disaster.
