ashes75, why aren't you considering SIPA?
My concern with the SSP is the atmosphere. Mostly evening classes and a large part time student body is not very appealing to me since I really believe that outside the classroom learning really important. I guess though that you could make the argument that SSP is in DC where all the action is happening. But it's not like we're sitting in on NSC meetings. Also I'm concerned about ideology. My interest in security are more in the "softer" security issues, and all of the classes and Professors seem to be interested in the more traditional and perhaps conservative and "hard" security issues. I like being challenged but I don't want to spend 1.5 years fighting. On the other hand you're right, the professional experience of the SSP Professors is really impressive.
I like the flexibility of the Fletcher program and the general Fletcher outlook. I'm American but have lived abroad for most of my life, so the international focus is important to me. Only 3 security classes just doesn't seem like very many to me. I suppose my 2nd Field of Study could supplement that, but 3 still sounds like so few.
