This is why leftist terrorism is rare. We have seen it in the past during the Cold War

the weather underground did a little bit, and there was some anti-war sabotage in shipyards and that bombing in wisconsin but overall it didn’t amount to much. If we go back to the “propaganda of the deed” days and Czogolz’s assassination of president mckinley i’d say it even backfired pretty hard as that lead somewhat directly to the creation of the FBI.
