I would recommend this for tactical level leadership. I would not recommend it for strategic level leadership or policy decision-making. 

I admire Rorke Denver's dedication, drive and optimism as well as the service he has provided to our country. We wouldn't necessarily agree on all political points, but I am proud to have had the opportunity to serve, in much less intense conditions, the same country he has served.
