(Aside: I suspect that we may see World War 3, replete with conscription, rationing and a full-scale war economy, within a few years at most. Even if the US, UK and Australia have enough troops and high-tech weapons to hold Afghanistan and Iraq, that will not be enough to invade Iran, Cuba, North Korea and Libya and put down the Saudi insurrection. And the invasion of Iraq is likely to add fuel to the fire.)
