“International politic world changes everysecond, the changes that happen is unpredictable. Si Vis Pacem Para Bellum, as simple logic is real. If we want peace then prepare for war. Example is what North Korea does in recent. United States deals with South Korea and Japan to built anti-nuke system in Seoul. In response, North Korea tests their nuke, its more about the way to defense. Another perspectives, there is also ‘psychology war’ between countries. The way to response and viewing their own military power. Do their fights physically? Not yet. The theory called balance of power lead this event, so the war is more psychological than physical.”
Just my two-cents. Paragraph you’ve read above is my answer to my exam question on subject International Security. As an International Relations student, the subject is interesting, wondering to learn more and again.
