They were probably their snow-camouflage uniforms (all white), and we’re supposed to believe they’re Klansmen.
Oh, good point.

Other countries
Aside from Canada, there have been various attempts to organise KKK chapters outside the United States. In Australia in the late 1990s, former One Nation founding member Peter Coleman established branches throughout the country,[184][185] and in recent years the KKK has attempted to infiltrate other political parties such as Australia First.[186] Recruitment activity has also been reported in the United Kingdom,[187][188] dating back to the 1960s when Robert Relf was involved in establishing a British KKK.[189]
In Germany a KKK-related group, the European White Knights of the Ku Klux Klan, has organised and it gained notoriety in 2012 when it was widely reported in the German media that two police officers who held membership in the organisation would be allowed to keep their jobs.[190][191][192] A group was even established in Fiji in the early 1870s by white settlers, although it was put down by the British who, although not officially established as Fiji’s colonial rulers, had played a leading role in establishing a new constitutional monarchy that was being threatened by the Fijian Klan.[193] In São Paulo, Brazil, the website of a group called Imperial Klans of Brazil was shut down in 2003, and the group’s leader was arrested.[194]
