I wonder what affect the eventual US pull back from Iraq will have, and we also cannot forget the likely possibility that we will see continued terror attacks. A large attack could have an enormous affect on our economy. Home prices fell last year even though the economy was rocking, interest rates were at historical lows, we didn’t see a major terrorist attack at home, unemployment was at historical lows and on and on and on. If one or more of these pillars of strength were to fall, then what happens?
