That difference raises the question of whether it is worth striving for a United States of Europe – a concept that many refuse to accept, because they do not believe in the possibility of a unified European identity. A single political system like that of the US, they insist, presupposes a common language and a single nationality.
这一不同引出了一个问题：是否值得为欧罗巴合众国而奋斗。许多人拒绝欧罗巴合众国这一概念，因为他们不相信欧洲有可能会产生同一的身份。他们坚持认为，像美国那样的单一政治体系需以共同语言和单一民族成分为条件。
