Why not surreptitiously drop oil-eating bacteria into Middle Eastern oil wells?
Enviros would be happy due to reduced petroleum supplies.
Western oil companies (few, if any, of whom have any drilling interests in the MidEast) would be happy due to reduced supplies increasing prices for their oil.
Alternative energy interests would be happy (due to generally rising petroleum prices).
The only losers are the MidEastern oil states, and those who are dependent on specifically MidEastern oil extraction (including, for instance, Islamic terrorist groups).
