I don't think we can escape the triggers until we take the power away from the memories. Once the memories don't have that control then the triggers should ease up. But how do you take away the power from so many different trauma memories? We will never not have the memories, and yet we have good memories that are triggered in a good way. Like the smell of fresh snow, the smell of puppy breath, those can trigger some good memories for me.
So triggers and memories will be around forever. And since it's not always known what will trigger what , we would need to work on those bad memories and take away that power that makes them so bad. Does this make sense?
