Throughout the crisis, European leaders have tried to respond to the gaps in the monetary union without proposing a new treaty, because they fear that any new treaty proposing more centralization of authority in Brussels would be rejected, either by national parliaments or by voters in a referendum. So they have tried to proceed by intergovernmental agreement, or by using existing treaty provisions.
在危机期间，欧洲的领导人们尝试去在不提出一个新条约的情况下对货币联盟内的分歧做出回应，因为他们害怕任何要求把权威更加向布鲁塞尔集中的新条约都会遭到否决——要么被各国议会，要么被参与全国公投的民众。
