The Guardian view on the united Ireland debate: shifting dynamics need to be treated with caution
Donald Trump’s blithe comments at the weekend were characteristically unhelpful. A careful and considered discussion on the subject has yet to begin

TL;DR
- The DUP believed Brexit would prevent a united Ireland, but it led to an Irish Sea border and increased North-South economic ties.
- Demographic shifts in Northern Ireland and Sinn Féin's election victory have accelerated discussions about constitutional change.
- Donald Trump's comments on unification, while welcomed by some, highlight the need for careful and prepared public debate.
- A sober, lengthy, and detailed public conversation is necessary to discuss the implications and potential outcomes of a united Ireland.
- Gordon Brown emphasized that unification would be a long process requiring agreement among people.
