Star Trek fans have become very sensitive to introductions of new characters, aliens or historic events arguing that things that haven’t previously been mentioned ‘break canon’ or disrespect lore.
This piece by Inverse shows how profoundly TNG retconned Federation, Starfleet, and main characters’ history on the fly.
Worth thinking about.
Respectfully, I think this is a bit of a retcon of the retcon.
“The Wounded” makes it seem like a fairly major conflict - certainly more than just “peacekeeping.”
