Middle East political rant (warning)
Evidently a car bomb exploded in Iran today. Sunni group may be perps. Americans were blamed for instigating the Sunnis. Some day these folks need to take credit for the chaos they cause.
As 'good' as current leadership is they didn't provoke this old, longstanding, sectarian fight. What astounds me is that current leadership underestimated the simmering social issues and overestimated their ability to manage the resulting chaos. IMHO the American military cannot quell this in Iraq, we should just get out of the way and let them figure this out.
