This article by Chris Hedges scares the everything out of me, and does not seem like partisan fear mongering.  I wonder if the Afghanistan Papers were indirectly responsible for our recent drone strike.

A war with Iran would see it use its Chinese-supplied anti-ship missiles, mines and coastal artillery to shut down the Strait of Hormuz, which is the corridor for 20% of the world’s oil supply. Oil prices would double, perhaps triple, devastating the global economy. The retaliatory strikes by Iran on Israel, as well as on American military installations in Iraq, would leave hundreds, maybe thousands, of dead. The Shiites in the region, from Saudi Arabia to Pakistan, would see an attack on Iran as a religious war against Shiism. The 2 million Shiites in Saudi Arabia, concentrated in the oil-rich Eastern province, the Shiite majority in Iraq and the Shiite communities in Bahrain, Pakistan and Turkey would turn in fury on us and our dwindling allies. There would be an increase in terrorist attacks, including on American soil, and widespread sabotage of oil production in the Persian Gulf. Hezbollah in southern Lebanon would renew attacks on northern Israel. War with Iran would trigger a long and widening regional conflict that, by the time it was done, would terminate the American Empire and leave in its wake mounds of corpses and smoldering ruins. Let us hope for a miracle to pull us back from this Dr. Strangelove self-immolation.
