CEVAP:

Heywood notes that a great power is “deemed to rank amongst the most powerful in a hierarchical state-system” and identifies four criteria for being a member of this so-called “great power club”:                                                                                                                           • “Great powers are in the first rank ofmilitary prowess, having the capacity to maintain their own security and, potentially, to influence other powers.
 • They are economically powerful states; although (as Japan shows) this is a necessary but not a sufficient condition for great power status.
 • They have global, and not merely regional, spheres of interests.
 • They adopt a ‘forward’ foreign policy and have actual, and not merely potential, impact on international affairs” (Heywood, 2011: 7).
