Global guerrillas are getting extremely adept at attacking systems. Iraq was hit with a multi-infrastructure cascade of failure on Tuesday. Saboteurs blew up oil pipelines at a juncture where they cross the Tigris River (co-location dependency -- See Infrastructure Meltdowns for more). This cut exports via Turkey. The pipelines also feed the nearby Beiji power plant (input and mutual dependency). The oil flowed down onto the water and created a sea of flaming oil. The Beiji plant was immediately shut down due to fears of fire spreading to the plant (update, it is claimed an adjacent cable shorted and shut down the powerplant). This rapid shutdown resulted in a wave of cascading electrical failures throughout the entire country (see Cascading System Failure for more). At one point the ALL of Iraq was without power.
This attack demonstrates a qualitative improvement in system attacks, the quantitative improvement can be seen in the attached graphic from Brookings. Oil exports are a mere ~60% of stated goals (and still below pre-war levels). Total losses from oil system disruption now exceed $2 billion. Electricity production is likely (no good data is available, but anecdotal information is available) half of demand -- not nearly enough to support economic revival.
