Ireland will, in less than 20 days, mark the 22nd anniversary of the Good Friday Peace Agreement.
There will be no parades; modest commemorations once planned have been deferred.
Despite that, the agreement remains the only legitimate blueprint for how relationships on this island can and will develop.
It was endorsed by a 32-county vote in as clear a declaration of democratic intent as this island’s history can provide.
Force was taken out of the equation.
Yet, there are still those, albeit a tiny minority, who imagine the peace agreement unimportant, irrelevant and something other that as clear a statement of intent as any society could make.
There are still those who imagine that their profoundly anti-democratic delusions about terrorism might reshape this island despite bitter and bloody evidence to the contrary stretching across the centuries.
Gardaí this weekend uncovered bomb-making operation at a disused quarry.
Three suspected “dissidents” were arrested — though if language is to have any integrity the word “dissident” in this context is an cheap evasion and denial of reality.
Gardaí believe those involved were highly experienced in terrorist engineering and that the devices being manufactured were designed for car-bomb attacks on PSNI officers.
This cancer must be purged and it is hard to think of measures too dramatic to achieve that — and to restate the freely-offered decision of voters north and south.
