LONDON -- In hard news terms, it's been one of the slower years: no great events, few surprises and no real shocks. But as the little events accumulated during 2006, the shape of the future gradually became clearer in three important dimensions.

It is now clear that America's moment in the Middle East is coming to an end. It has been a rather long moment -- the United States has called most of the shots in the region since the 1960s -- but recently it has turned into a classic case of imperial over-stretch.

So we will soon find out if a strong American presence really was vital for all of those years to keep the oil flowing, keep the crazies from seizing power, and keep Israel safe.
