Historically, the international community would have targeted weak states for territorial absorption or colonial domination or, alternatively, such states would fragment into pieces small enough to be effectively administered and secured by a local power. However, international norms towards sovereignty changed in the wake of World War II in ways that support and maintain the existence of weak states. Weak states are given "de jure" sovereignty equal to that of other states, even when they do not have "de facto" sovereignty or control of their own territory, including the privileges of international diplomatic recognition and an equal vote in the United Nations. Further, the international community offers development aid to weak states, which helps maintain the facade of a functioning modern state by giving the appearance that the state is capable of fulfilling its implied responsibilities of control and order. The formation of a strong international law regime and norms against territorial aggression is strongly associated with the dramatic drop in the number of interstate wars, though it has also been attributed to the effect of the Cold War or to the changing nature of economic development. Consequently, military aggression that results in territorial annexation became increasingly likely to prompt international condemnation, diplomatic censure, a reduction in international aid or the introduction of economic sanction, or, as in the case of 1990 invasion of Kuwait by Iraq, international military intervention to reverse the territorial aggression. Similarly, the international community has largely refused to recognize secessionist regions, while keeping some secessionist self-declared states such as Somaliland in diplomatic recognition limbo. While there is not a large body of academic work examining the relationship, Hironaka's statistical study found a correlation that suggests that every major international anti-secessionist declaration increased the number of ongoing civil wars by +10%, or a total +114% from 1945 to 1997. The diplomatic and legal protection given by the international community, as well as economic support to weak governments and discouragement of secession, thus had the unintended effect of encouraging civil wars.
