I braved an interview by David Gregory to listen to General David Petreaus.
The message:
The military has a process. Trust the process, which will divorce individual opinion from institutional approach (for lack of a better term), and don't get the military too politicized on the emotions surrounding the topic.
This is sensible in terms of policy implementation. There is nothing sensible about the political process, however. Disagreements within the military will be amplified. Is it too much to hope for, in terms of a univocal recommendation from the brass? Probably.
