When it comes to disruptions from outside, the Northern Ireland conflict has a reputation for being immune to them. Winston Churchill observed this after the first world war, in one of the most quoted remarks on Irish politics:
A century later, the "integrity of their quarrel", for the most part, remains. That said, external developments like the US civil rights campaign, the end of the cold war and the EU have influenced events in the region.
So far, the coronavirus pandemic has interacted with Northern Ireland politics in some intriguing ways. At the beginning of the crisis in mid-March, the cross-community executive became split on whether to follow Dublin's lead in immediately closing schools or stick with the UK's more relaxed approach.
Yet since then, the first and deputy first ministers, Arlene Foster and Michelle O'Neill, have maintained a mostly united front. This has been in contrast with the three years before January 2020, when their parties wouldn't work together, leaving Northern Ireland without devolution. The mere sight of Northern Ireland's provincial politicians, schooled in the tribal minutia of a nationalist conflict, battling a global natural disaster has been arresting.
North-south co-operation has also been in the spotlight. This is a key part of the Good Friday Agreement. While Belfast and Dublin agreed they would share information on the virus, deficiencies in coordination have been exposed.
Another feature of the crisis in Northern Ireland has been the outpouring of support for the NHS from across society. Remarkably, murals praising this (British) institution have appeared in both unionist and nationalist areas.
Does any of this matter? When the deluge of COVID-19 subsides, there are three possible scenarios. The first is, of course, that there won't be any long-term consequences of the pandemic and that political life picks up mostly where it left off.
However, the pandemic could, on the other hand, worsen divisions. Stormont now has its own roadmap out of lockdown, which is different to those of both London and Dublin. This has cross-community support but there is still plenty of room for unionists and nationalists to split over virus policy.
Anger at the Conservative government's handling of the crisis, and the prominence of the devolved administrations, could hasten the end of the UK, with all the tumult that would bring to Northern Ireland. Paramilitary murders and threats have continued during the shutdown. And the dreary steeples of Brexit have never been fully out of view.
A chance to change
But a third possibility - and narrowly, the most likely - is that the virus, overall, has a stabilising influence. It could put political identity politics into perspective.
While COVID-19 is an external shock, it has shone a light on existing social realities: inequality; challenges in education; the quality of people's environment, lifestyle and relationships; and above all, the health service. Public interest in these issues may increase over Orange-Green politics.
As the success of the non-aligned Alliance Party and Greens in the 2019 election showed, this process was already under way. Before the crisis, the main parties knew that the current period of devolution could be the last chance they get to show the public that they can govern effectively. The socio-economic damage of the shutdown may stimulate bold, unprecedented policy solutions.
Irish republicans have argued that the pandemic, which respects no borders, proves the illogic of partition on a small island. But pandemics, we hope, will not be something Ireland or any country has to face often. And the problem of differing strategies between neighbouring countries is not unique to Ireland, but has been felt across Britain and Europe. The crisis may actually slow the momentum of the Irish unity discussion, which had been given so much oxygen by Brexit, especially given the looming financial pressures.
When the dust settles, Northern Ireland could have a stable executive focused on everyday politics in the north, pragmatically aligned with Dublin or London or Brussels on particular issues. In other words, the region could find itself closer to the vision of the Good Friday Agreement than it has been for some years.
What is beyond doubt is that sectarianism, Northern Ireland's local brand of social distancing, offers no protection from an infectious disease. Whatever its legacy, COVID-19's indiscrimination proves that the physical space is in fact a shared one. Those who live in that space share the same fate, no matter the imagined national communities to which they purport to belong.
