US history is full of covert & non-covert operations with the single objective of gaining more access to oil. Some of these operations have involved the overthrow of democratically elected governments by various means including assasination of important political figures, discrediting politicians and also the obstruction of new governments implementing promised policy objectives. This is well known and documented history from released US government and CIA files.
Just read about the meddling in Iran (since 1953) and Iraq since 1917. The orchastrated overthrow of governments in South America, the Iran contra affair etc. It goes right to the top.
