I think no commander ever is going to come out and say, 'I'm confident that we can do this.

Items of interest will be located, identified, monitored, and remotely controlled through technologies such as radio-frequency identification, sensor networks, tiny embedded servers, and energy harvesters - all connected to the next-generation internet using abundant, low-cost, and high-power computing.

In Afghanistan you are not rebuilding, you are building. There is very limited infrastructure and extreme terrain, with deserts in the south and mountains so high in some areas that helicopters don't even fly well at a certain altitude because the air becomes so thin. The country has a serious problem of illiteracy, especially after so many years of war and Taliban rule.

The Sunni Arabs began to realize that they had made a huge mistake by not voting in the election of 2005 and by not being part of the new Iraq. They had reasons for this: They were effected by the disestablishment of the military and by de-Baathification (the dismantling of Saddam Hussein's party) in winter 2007-2007. They increasingly recognized that their future lay in being part of the solution rather than a continuing part of the problem.
