There have, of course, been many examples in history in which currency unions or single-currency states have broken up. Although there are technical and legal reasons why such a split would be harder for an EMU country, there seems little doubt that a country could withdraw if it really wanted to.
当然，历史上有很多货币联盟或单一货币国家分裂的例子。虽然对欧洲经济与货币联盟成员国来说，因为技术和法律上的原因，这样的分裂更为困难，但是，如果欧洲经济与货币联盟成员国真地想退出，就可以退出，人们对此的疑问似乎很少。
