By exiting the EU, the UK would severely damage its economic interests, losing both the single market and London’s role as a financial center. An exit would also harm Britain’s geopolitical interests, both in Europe (where, ironically, it favors EU enlargement) and, worldwide, in its global standing and special relationship with the United States (which has made clear its preference for a European UK).
毫无疑问，脱离欧盟的英国也能生存，但生存质量如何就难说了。退出欧盟会严重损害英国的经济利益，既失去了单一市场，也丢掉了伦敦的金融中心地位。退出欧盟也会危害英国的地缘政治利益，不仅包括其在欧洲的利益（讽刺的是，这方面它倒是支持欧盟扩张的），也包括其在全世界的利益，其在全球事务中的地位以及其与美国的特殊关系（美国明确表示更希望看到欧洲英国）。
