The belief that openness is treason and closure is patriotic is a rejection of the entire post-1945 framework of politics and policy in the developed world. It is an attempt to turn back the clock to the interwar period, when the focus was on closing off: imposing onerous trade restrictions and persecuting or expelling minority groups.
开放就是卖国，封闭就是爱国，这一信念是对1945年后发达世界政治和政策框架的全盘否定。这是试图开历史的倒车，回到两次大战之间的时代，当时的主题就是封闭：采取严厉的贸易限制，迫害或驱逐少数群体。就连美国也是如此——它实施了建国以来最严格的移民法。
