Brigadier-General James Ellery CBE, the Foreign Office’s Senior Adviser to the Coalition Provisional Authority in Baghdad since 2003, confirmed the critical role of Iraqi oil reserves in potentially alleviating a “world shortage” of conventional oil. The Iraq War has helped to head off what Brigadier Ellery described as “the tide of Easternisation” – a shift in global political and economic power toward China and India, to whom goes “two thirds of the Middle East’s oil.”

If it wasn’t clear before it should be now: the Bush Administration can’t afford to attack Iran. With gas already at $4 a gallon and rising almost every day, Iran figuratively and literally has the United States over a barrel. As much as the Administration is tempted, it is not about to test Iran’s promise to “explode” the Middle East if it is attacked.

The Iranians haven’t been shy about making clear what’s at stake. If the U.S. or Israel so much as drops a bomb on one of its reactors or its military training camps, Iran will shut down Gulf oil exports by launching a barrage of Chinese Silkworm missiles on tankers in the Strait of Hormuz and Arab oil facilities. In the worst case scenario, seventeen million barrels of oil would come off world markets.

Convinced the planet’s oil supply is dwindling and the world’s economies are heading for a crash, some people around the country are moving onto homesteads, learning to live off their land, conserving fuel and, in some cases, stocking up on guns they expect to use to defend themselves and their supplies from desperate crowds of people who didn’t prepare.

We rely on it to power our everyday lives, and it drives the economy worldwide, but oil faces an uncertain future in the 21st century. Black gold is increasingly expensive, environmentally damaging and, in the view of some experts, increasingly scarce.

Rising oil prices, global food shortages and the economic crisis are proof for many survivalists that society is on the brink of meltdown. But are their predictions all gloom and doom - or a chance to create new communities?
