Security studies in 21st century face with complex and uncertain international trends: 1) rise of emerging powers (how do emerging powers change the international security order?), 2) asymmetrical threats (terrorism and insurgency activities), 3) proliferation of weapons of mass destruction and conventional weapons, 4) emerging importance of new domains (space and cyberspace). Throughout this semester, this course will conduct in-depth lectures and discussion dealing with these emerging trends of international security.
