This is related to an observation which could bring some hope.
Blogger Julia Gorin quotes James George Jatras, a former U.S. Foreign Service officer and foreign policy analyst for the U.S. Senate Republican Policy Committee, as saying:
In some ways, we [Bukovsky, Jatras, and their friends] were the heart of the Administration’s anti-communist line and the “fathers” of the National Endowment for Democracy. (As opposed to the prevailing view that communism was forever and we needed permanent detente with the Soviet regime. Looking back from today, it’s hard to believe how ingrained that view was). [Emphasis added]Similarly, today Europeans think that mass immigration from the Third World and multiculturalism are here to stay for good.
Journalist and author Christopher Caldwell writes in his book Reflections on the Revolution In Europe: Can Europe Be the Same with Different People in It? (Amazon US) (Amazon UK):
It is often noted with shock how long it took for European natives to realize that immigrants had settled in Europe to stay. Europeans went on thinking that immigrants would simply “go home” until at least the 1970s, when France first established programs to pay immigrants to repatriate themselves, and in some cases well into the 1980s. Today, however, Europeans often make the opposite mistake. They exaggerate how well established immigrants are in Europe. In high-immigration countries like Spain and Italy, the overwhelming majority of immigrants are first generation, and even in the oldest immigration countries, the immigrant population is much less rooted than it appears. In 2000, 60 percent of Germany's vast foreign population had arrived after 1985. Plenty of immigrants are full members of the society of their new homeland, with full claims on it. Just as many are not. [Emphasis added]
