When they are guests of authoritarian regimes? With money and weapons and technical expertise not available in the rest of the population? If you don’t think they would have an effect on the culture, you are amazingly naive.
And it wasn’t a mere thousand: “German prosecutors who examined secret files from Brazil and Chile discovered that as many as 9,000 Nazi officers and collaborators from other countries escaped from Europe to find sanctuary in South American countries. Brazil took in between 1,500 and 2,000 Nazi war criminals, while between 500 and 1,000 settled in Chile. However, by far the largest number — as many as 5,000 — relocated to Argentina.”
I’m stunned at the Nazi defenders on this site.
