Will the next election in N.Ireland be a game changer with the DUP exiting the scene and allowing the country to move forward - How soon?

In the end, the purse is more powerful than the pulpit. If the people of Northern Ireland see a more prosperous future in the EU then they may well decide to join the Republic. Hardliners will not soften their attitudes but even they would accept a united Ireland if safeguards for their beliefs were built into the deal and prosperity was the prize. The key feature is the size of the reasonable centre — those people who value peace and prosperity above sectarian allegiance. That group appears to be growing. Perhaps the outcome of the Brexit agreement will prompt an increase in their numbers and tip the balance towards a united island.

The Ireland of old has gone- it will never be the same again. If the next election is a game changer then so be it but at the moment there is no one governing there! It is up to the people.

No Sinn Fein and the DUP will remain the largest parties but the nationalist population is out breeding the unionists so in 20 years time there will be a large nationalist majority of voting age so a United Ireland is inevitable

that will be up to the alliance and OU parties to win at their expense.

What will happen in Northern Ireland is for them to decide and not by outsiders.

i think the DUP might secretly want a return to conflict, i honestly think if the trouble started up again it would benefit them in so much as it would push a united ireland further away

It is impossible to predict the future, so as to if and when, impossible to say. I doubt the DUP will exit the scene but you can keep hoping, but what will they be replaced with, are 't there enough former killers tangled up in northern Irish politics?
