* Hans Janmaat recently became the first avowed fascist candidate to be elected to the Dutch parliament since World War II.
* In neighboring West Germany, Chancellor Helmut Kohl made a point in his first leadership declarations to state that he would try to resolve the problem represented by the presence of some 5 million foreigners.
* And anti-immigrant positions, declarations, and pamphlets figured prominently in the Belgian municipal election campaign that ended last week.
These recent examples of Western European unrest over the estimated 9 million foreign workers and their families in their midst, are only the latest in a long string of such episodes.
There have been bloody riots with racial undertones in recent months in the Brixton section of London; fights between rampaging teen-age gangs of Turkish immigrants and local skinheads in Stockholm; and openly anti-immigrant campaign oratory by the French Communist Party in the 1981 presidential elections.
Other expressions of concern at the international level have also surfaced in recent months from the International Labor Organization (ILO), which warned of ''the time bomb'' in Western Europe represented by millions of young immigrant children facing even greater problems of integration and employment.
Confronted with this potentially explosive problem of millions of foreigners imported during the economic boom years of the 1960s, European governments have reacted in different ways.
Most have sought to block new arrivals and even to stimulate a reverse flow of departures through means ranging from financial repatriation bonuses to outright expulsion. Faced with rising unemployment, virtually all governments have sought severe curbs on new entries.
Such policies have strained relations between the host countries of Northern Europe and the traditional manpower exporters around the rim of the Mediterranean. It has become a source of some friction between the nations in the European Community (EC) and the new or candidate states of Greece, Spain, and Portugal over the Community's existing laws promising free movement for its citizens throughout the territory.
