In Switzerland now: it’s a mess.

More than 20 percent of Swiss inhabitants are foreign nationals, and the SVP argues that a disproportionate number are lawbreakers. Many drug dealers are foreign, and according to federal statistics, about 70 percent of the prison population is non-Swiss.

As part of its platform, the SVP party has begun a campaign seeking the 100,000 signatures necessary to force a referendum to let judges deport foreigners after they serve prison sentences for serious crimes. The measure also calls for the deportation of the entire family if the convicted criminal is a minor.

Human rights advocates warn that the initiative is reminiscent of the Nazi practice of Sippenhaft, or kin liability, under which relatives of criminals were held responsible and punished for their crimes.

The party’s political campaign has a much broader agenda than simply fighting crime. Its subliminal message is that the influx of foreigners has somehow polluted Swiss society, straining the social welfare system and threatening the very identity of the country.

Unlike the situation in France, where the far-right National Front leader Jean-Marie Le Pen campaigned for president in the spring alongside black and ethnic Arab supporters, the SVP has taken a much cruder us-against-them approach.
