 note = {application/pdf, After the end of the Cold War, the North Atlantic Treaty Organization （NATO）redefined its self-image as an Alliance who would be dedicated to serving international peace and stability by embracing the principles of collective defense and cooperative security. After the Russo-Georgian War （2008） and the Ukrainian Crisis （2014） on one hand, to counter Russia’s aggressive policy, NATO has strengthened collective defense postures among the member states, on the other hand, under the principle of cooperative security, it has developed partnerships with the former Soviet Republics of Georgia and Ukraine. Russia has strongly opposed to these NATO’s developments, followed by military and diplomatic tensions between the two parties. By saying so, this article concludes that today’s NATO unexpectedly faces the challenges stemmed from its collective defense and cooperative security policies.},
