Moreover, as Russia’s recent assertions of power in Ukraine and elsewhere in the former Soviet Union demonstrate, European countries need to deepen their security cooperation and develop a common energy policy. And, though cooperation in areas such as of data privacy, financial-sector regulation, and climate change may not require the degree of political integration that a common currency does, it would benefit greatly from stronger political cohesion and a more profound sense of shared European identity.
此外，俄罗斯最近在乌克兰和其他前苏联地区耀武扬威，这表明欧洲国家需要深化安全合作、发展共同能源政策。而尽管在数据隐私、金融部门监管和气候变化等领域的合作并不需要如共同货币那么深的政治一体化程度，但加强政治团结、深化欧洲身份的认同感能够带来巨大的裨益。
