Before enlargement, it was politically incorrect to discuss possible waves of migration to the West, as EU politicians saw this as an obstacle to the enlargement process. Now that enlargement has taken place, it is easier to discuss migration objectively.
欧盟东扩前，谈论可能涌向西欧的移民潮在政治上是错误的，因为欧盟的政治人物认为这是对欧盟扩大进程的阻碍。现在东扩已经实现，客观地讨论移民问题就容易一点了。
