In yesterday's Taiwan Democracy Project Taiwan Democracy Project talk, Cortez Cooper noted the DPP has developed an extensive set of Defense and National Security Blue Papers which reflect the party's current thinking about national security issues. The development of these policy papers was done over the past two years by the New Frontier Foundation, the DPP's de facto policy think tank.  

The full set are posted below for reference. Source is here. 

On a related note, the Ministry of National Defense released the latest biannual Defense White Paper in November 2015. The report is currently available only in Chinese; the English version should be released soon. However, for readers who prefer to get their information about military affairs in graphic novel form, a comic book version is already available. Seriously.
