Where is this claim of yours documented with data? Let’s see that before going on to the victory lap.
The Venona Papers confirms many of those accused (conveniently years after the fact).

M. Stanton Evans’s book, “Blacklisted by History”, cited many times in this thread, also goes into detail.
I wouldn’t use language like (going on a) “victory lap” in confirming their guilt. The damage was done by these individuals and others, and was incalculable. The only victory would’ve been stopping it before it happened.
