The First World War, a conflict where the major European protagonists had a strong sense of moral purpose but little in terms of concrete objectives, was made possible by the crystalisation of national identities in the years immediately preceding it.
The results of last week's voting across the continent reveals that we are some way into a new phase, where the national community is in crisis, and knows it. This manifests itself as a straight conflict of interest between the rooted and the consciously uprooted. Some of the latter are comparatively poor and seeking better opportunities across nearby borders, but many belong to the globalised urban elites, who have found that they owe much of their disproportionate affluence to a transnational perspective, and are thus inclined to favour the far-reaching technocratic institutions which appear to underpin their future economic wellbeing.
The comparatively rooted meanwhile strongly suspect that they are getting the raw end of the deal (which they are...) And yet, I surmise, they must also deep down suspect that there is no going back to the way things used to be, that semi-mythical past when government policies and budgets were constructed primarily in the interests of the clearly-situated taxpayers of the nation state.
And one suspects that also, on some subconscious level at least, they have recognised the essentially - annoyingly - reasonable nature of the counter-argument that the smug globalised elites have deployed, because their own protests - be they Tea Party activists, Scottish secessionists or immigrant-phobes - have become increasingly counter-rational (when not economically suicidal) and, in the immediate term, this can surely only be further damaging to democracy.
I've had some direct experience of a mirco-cosmic version of these tensions as I used to make a living working both for a company and beyond it. And of course the likes of WPP, Starbucks, Google and Apple are doing the same thing with regards to nation states and their regulations (and other limitations).
In both cases the key argument for such practices is that they are both the way of the future and a technique for increasing the big numbers for all. These bigger numbers do not however necessarily translate into the sort of universally lifting boats that rising tides are supposed to produce.
So the rooted are right to question the new status quo, at least as it is currently structured. What worries me is that people are turning to emotional, counter-factual, self-defeating platforms in response. Whatever 'good arguments' exist for blocks like the EU or indeed the UK, will be ignored by people who have simply decided to switch off their brains out of pique for the way they have been treated.
