Sinn Féin is tilting at windmills
Ireland’s neutrality is an important and valued principle that is copperfastened already in law and the Constitution
There is a tendency on the left and right of politics to see enshrining a principle in the Constitution as a decisive gamechanger, a way of ending an argument in perpetuity. A large part of the rationale seems to be that the Dáil can not be trusted in the long term to uphold key principles and must have its hands shackled permanently by constitutional prohibition.
Such a lack of faith in the democratic rootedness of the the Dáil notwithstanding, it also seems that we refuse to learn from the difficult experience of repeated abortion amendments: firstly, that such questions are never closed by a constitutional provision, and, secondly, that the Constitution is not a sensible home for detailed policy provisions rather than the broad principles underlying it which can be operationalised by the Dáil.
