Following his second tour in Iraq, Petraeus authored a widely read article in "Military Review", listing fourteen observations he had made during two tours in Iraq, including: do not do too much with your own hands, money is ammunition, increasing the number of stakeholders is critical to success, success in a counterinsurgency requires more than just military operations, ultimate success depends on local leaders, there is no substitute for flexible and adaptable leaders, and, finally, a leader's most important task is to set the right tone.
