Eh, sorry to burst your bubble, but not really true about Tito. Plenty of Nazis and their collaborators lived their lives through the socialist period and were rehabilitated with honors after the anti-communist nationalists took over in the 1990’s.

The one single example where they did execute a lot of them was, when they were trying to run away to the West killing and burning their way through in the process, even after the Nazi Germany capitulated. They reached the British forces, who returned them to Tito’s partisans…many of whom, with their families, suffered greatly from these Nazis.

To this day Croatian Nazis are holding a memorial on that location (in Austria) backed by the Croatian parliament funds. Memorial was infamous for open displays of Nazi ideology until even Austrians got fed up with it…

The reprisals against Italian fascists and their collaborators were so small in scale, they are rarely even mentioned.

Here’s an article fromAljazeera I googled from 5 years ago and is still relevant. https://www.aljazeera.com/news/2018/5/11/bleiburg-far-right-croats-to-mourn-wwii-dead-in-austria
