The American national security establishment is shifting from nation building to addressing the challenge of rising great powers, from a near obsession with the United States Central Command geographic area of responsibility to an emphasis on the Indo-Asia-Pacific region. Sound familiar? This shift both reflects the trajectory of US policy today and echoes where the United States wanted to go 20 years ago, before the September 11 attacks derailed Washington’s intentions. As the United States embarks on a new national security approach, the nation would do well to remember events have a way of undermining the best-laid plans and strategies.
