The chance of a better life – or any life at all – is all but irresistible to the people trapped in these areas. No matter how strong the EU’s external borders are – though, of course, better monitoring and patrolling measures are needed – the flow of migrants will continue to overwhelm their capacity, endangering the openness that is so fundamental to European unification, beginning with the Schengen acquis, which guarantees freedom of movement, without border controls, among 26 European countries.
美好生活的机会——或者任何生的机会——在这些地区的民众看来都无法抗拒。无论欧盟的对外边界多么强大——尽管改善监管和巡逻措施确有必要——移民人数仍将继续超过他们的防御能力，从而对自申根协议始的开放这一欧洲统一的基础构成威胁，申根协议确保欧盟26个成员国民众在没有边界控制的情况下能够自由迁徙。
