Non Proliferation: Got this site off a Twitter run by Deputy Director, CNS and former nuclear advisor to Vice President Joseph Biden.
Russian Defense Policy: Well, its just that. News about how Russia plans offense and defense military decisions.
Russian Strategic Nuclear Forces: Self-explanatory. Much information here and updated often. Worth Bookmarking if you're working in the IC.
Free Syria Media Hub: 120,000 dead; 430,000 injured and 500,000 refugees make for very graphic visual images of the atrocities committed by Assad and his military in Syria.
I use these four sites often, including to find aritcles I can show on Twitter or Facebook that would be of interest to my Followers and Friends, respectively. The middle two sites proved current information about the Russian military. Enjoy!
