In the eighties a crashing oil price assisted in the fall of the Russian communist powerhouse. This is reported by some as a deliberate outcome orchesrated by the USA.
Today we have high oil prices (due to many factors) which is slowly sucking the lifeblood (money) from the energy dependant USA. Could we be seeing the reverse situation in progress? The Iranians have proven they are he-ll bent on hurting the USA fianancially, just see their European Oil bourse efforts. Inflaming the Middle East with talk of the future destruction of Israel and claims of enriching uranium are serving a purpose beyond provocation. Higher oil prices. Don't ignore the Russian connection to Iran either. Who do you think has supplied them with technology to create "supersonic" missiles? Perhaps a little financial advice on the side also. Is Russia working towards getting her revenge through the backdoor?
To further relate this theory, consider GW Bushes recent talk of advancing oil production in a move towards reducing oil imports. He is aware of this building financial crises and possibility that a crazy leader in charge of vast amounts of oil could tip the great USA over the edge, in a similar fashion to what they did to Russia.
Seems there is a huge ongoing play that is being acted out at this moment in time.
