in the Social Contract argued, "the growth of the State giving the trustees of public authority more and means to abuse their power, the more the Government has to have force to contain the people, the more force the Sovereign should have in turn to contain the Government," with the understanding that the Sovereign is "a collective being of wonder" (Book II, Chapter I) resulting from "the general will" of the people, and that "what any man, whoever he may be, orders on his own, is not a law" (Book II, Chapter VI) – and predicated on the assumption that the people have an unbiased means by which to ascertain the general will. Thus the legal maxim, "there is no law without a sovereign." According to Hendrik Spruyt, the sovereign state emerged as a response to changes in international trade (forming coalitions that wanted sovereign states) so that the sovereign state's emergence was not inevitable; "it arose because of a particular conjuncture of social and political interests in Europe." Once states are recognized as sovereign, they are rarely recolonized, merged, or dissolved. Post World War II world order Today, no state is sovereign in the sense they were prior to the Second World War. Transnational governance agreements and institutions, the globalized economy, and pooled sovereignty unions such as the European union have eroded the sovereignty of traditional states. The centuries long movement which developed a global system of sovereign states came to an end when the excesses of World War II made it clear to nations that some curtailment of the rights of sovereign states was necessary if future cruelties and injustices were to be prevented. In the years immediately prior to the war, National Socialist theorist Carl Schmitt argued that sovereignty had supremacy over constitutional and international constraints arguing that states as sovereigns couldn’t be judged and punished. After the Holocaust, the vast majority of states rejected the prior Westphalian permissiveness towards such supremacist power based sovereignty formulations and signed the Universal Declaration of Human Rights in 1948. It was the first step towards circumscription of the powers of sovereign nations, soon followed by the Genocide Convention which legally required nations to punish genocide. Based on these and similar human rights agreements, beginning in 1990 there was a practical expression of this circumscription when the Westphalian principle of non-intervention was no longer observed for cases where the United Nations
