The Center for International Maritime Security (CIMSEC) is a non-profit, non-partisan think tank. It was formed in 2012 to bring together forward-thinkers from a variety of fields to examine the capabilities, threats, hotspots, and opportunities for security in the maritime domain. Check out the NextWar blog to join the discussion. CIMSEC encourages a diversity of views and is currently accepting membership applications here.
