He was an 18 year old SS volunteer. Doubt there would be evidence against him individually other than voluntary service in the SS. Which would keep him out of the US. The 14th Waffen Grenadier Division of the SS fought against the Red Army and partisans. They’re implicated in war crimes, but mostly against civilians in areas of partisan activity. Interestingly both Russia and Poland are now investigating and his attendance is causing some embarrassment in Canada. Particularly over a memorial to veterans of the 14th SS Division. No way Trudeau didn’t know what he was doing.
Thanks!
