They offer lots of very sexy DL programs. (And even more on-site programs.) The thing with NPS is that applicants must be military officers or employees of selected government agencies. (I think that they accept employees of some civilian contractors too.) Applicants need to have endorsements from their military superiors or their employers. A number of programs and individual classes require that students have fairly high security clearances. (Dunno if the classified stuff is delivered by DL over the internet.) They do accept foreign students, but these have to hold equivalent positions (military or government) in selected allied countries. I expect that NATO is cool and I believe that they have students from Australia.
