In the course of the German reunification, Chancellor Helmut Kohl accepted the territorial changes made after World War II, creating some outrage among the Federation of Expellees, while some Poles were concerned about a possible revival of their 1939 trauma through a "second German invasion", this time with the Germans buying back their land, which was cheaply available at the time. This happened on a smaller scale than many Poles expected, and the Baltic Sea coast of Poland has become a popular German tourist destination. The so-called "homesickness-tourism" which was often perceived as quite aggressive well into the 1990s now tends to be viewed as a good-natured nostalgia tour rather than an expression of anger and desire for the return of the lost territories[citation needed].
