On 11th May 2013, the 2nd study meeting of the Peacebuilding Study Group was held in a conference room in the 80-nenkan building at Hosei University. In this meeting, three of the eight participants made presentations on the “Responsibility to Protect” (R2P) and the “Protection of Civilians” (POC), based on the UNU book “Norms of Protection: Responsibility to Protect, Protection of Civilians and Their Interaction.” First, Mr. Taichiro Fujino, who is a graduate student at Hitotsubashi University, made a presentation about the Chapter 1, entitled “Game Change and Regime Change.” He introduced the history of and arguments for and against R2P. Next, Mr. Shogo Yoshida, who is an undergraduate student at Hosei University, discussed Chapter 2, “The Protection of Civilians in Armed Conflict: Four Concepts,” and Chapter 3, “The Responsibility to Protect and the Protection of Civilians in Armed Conflict: Overlap and Contrast.” He explained the four types of POC: Combatant POC, Peacekeeping POC, Security Council POC, and Humanitarian POC. He also compared POC with R2P in terms of their similarities, interactions, and differences. Finally, Mr. Jason Pratt, who is a graduate student at Hosei University, spoke on the conclusion of the book and analyzed R2P and POC as they apply to the modern situation in Afghanistan.
