美国和古巴上月恢复外交关系；本星期古巴释放了一批政治犯。就像当年中美恢复正常关系带来一个新的中国一样，一个新的古巴也许从2015年开始了。
古巴国籍法律的现状是，不允许双重国籍，剥夺持双重国籍的本国国民的出生国籍。
而且，这种剥夺是直接通过国家法律来宣示的。
对于双重国籍，古巴宪法是这样写的: “古巴不承认双重国籍。所以，当一个人取得外国籍，其失去古巴国籍”（“Dual citizenship is not
recognized. Therefore, when a foreign citizenship is acquired, the Cuban one
will be lost.”）
对本国国民的出生国籍的尊重，和法律上对出生国籍的保护，是一个文明社会的最基本的标志。正因为如此，联合国《世界人权宣言》明确宣示：“不得任意剥夺一个人的国籍”。在中国几个“传统盟友”中，俄罗斯和越南等国家都已经先后改变国籍法律和国籍政策为不剥夺一个人的出生国籍，从而在不承认双重国籍的同时允许双重国籍。拭目以待古巴的双重国籍法律和政策的变化。
古巴用法律剥夺持双重国籍者的本国国民的出生国籍的现状，可以成为一面镜子，借以比较中国大陆的不剥夺出生国籍的国籍法律，借以比较和中国国籍法律相背离的由中国国务院侨办主导的剥夺出国人民的出生国籍的国籍政策。
