"In a way, even more than Stalin, Hoxha had a vision of 'socialism in one country'- not for geo-strategic reasons, but out of alleged ideological purity, which served as a convenient cloak for nationalism. This is different from isolationism, with which Albania is usually taxed. Rather, Tirana's policy has been one of absentation- refusing, for example, to participate in the European Security Conference (which Hoxha termed 'a conference of insecurity')."
