For me the modern North needs to be convinced by us that they will have a better future with us. (Perhaps through the EU)

There were terrible mistakes made by both sides in the last 100 years.
If there is to be a sustainable future then an objective look at our history is needed. Lessons should be learned including how to deal with untrustworthy British governments.
