As a father with baby #2 on the way I have been giving a lot of thought lately to the challenges facing America over the next 92 years. In my analysis the greatest threat we still face is a global war against another industrial power. It may be that you can take the boy out of the cold war but you cant take the cold war out of the boy. I still feel strongly that global terrorism is a threat on a local/regional level but does not pose a general threat to continued US hegemony. As the next 100 years will probably remove oil as the primary lubricant of capitalism, I can see the Middle East becoming less and less relevant politically over the next 50 years. While many people seem to lump Iran into the terrorist threat camp, I do appreciate the threat posed by a nuclear Iran and support exploring all options to limit their acquisition of nuclear weapons. Iran is also the only Middle Eastern country that possesses a significant indigenously developed industrial base (ex. Israel). Another significant issue will be the emergence of China as a true rival for US economic and then Military power. We have a lot of experience in dealing with Russias global aspirations but China is far more difficult. As we have employed China as a counter to Russia for the past 40 years we will probably need to develop a bond with India to counter Chinas expansion of power. Anyway, does anyone have an opinion they would like to share with the group?
