In a globally integrated economy, the biggest challenge is to make sure there is adequate global aggregate demand, achieved through spending, when countries like China feel they must save high levels of dollar reserves to protect against international currency volatility.

One of the real costs of the war is that our security is actually less than it otherwise would have been - ironic, since enhancing security was one of the reasons for going to war. Our armed forces have been depleted - we have been wearing out equipment and using up munitions faster than we have been replacing them; the armed forces face difficult problems in recruitment -by any objective measures,including those used by the armed forces, quality has deteriorated significantly.

I'm writing from New Zealand - a country that decided from the beginning that the War was wrong, and chose not to participate in Iraq War.

I went to public schools, and while Gary was, like most American cities, racially segregated, it was at least socially integrated - a cross section of children from families of all walks of life.

I think what they've been doing is largely almost in firefighting mode without a good conceptual framework - either at the micro or the macro level. Micro, you would ask: "What kind of financial or banking system do we want?" Macro, you would say: "What are the underlying problems in the structure of our economy?"

You saw on your TV what happened in New Orleans after Hurricane Katrina. The Reserves or National Guard are usually the people we use for those national emergencies. They weren't here, they were over in Iraq, and so we were less protected.

China's accumulation of reserves is a result of the IMF's mismanagement of the Asian financial crisis a decade or so ago. If countries know they can't rely on the IMF to help them, their best defense is their own reserve cushion. In a time of spreading global recession, too much emphasis on savings in surplus countries like China can impede prospects for global growth.
