Northern Ireland, partition, and British shipbuilding capacity

How would Northern Ireland leaving the United Kingdom affect Britain, and why is the historical partition difficult to reduce to a simple colonial decision?

Britain would lose important shipbuilding suppliers, while the partition itself reflected conflicting local preferences and a serious risk of civil war rather than one obvious settlement.

Britain would lose access to Harland and Wolff and other Northern Irish suppliers if the territory left the United Kingdom. Modern Northern Ireland also resists a simple colonial label. At partition, a substantial armed minority opposed inclusion in an independent Ireland, so forcing one all-island outcome risked civil war rather than resolving the conflict. County-by-county votes might have reflected local preferences more closely, but they could also have produced an even more fragmented border and still left no clean answer.
