The Financial Times recently headlined warnings from leading economists about the dangers of Brexit. I expected something more forthright when I read the article. They were hedging their bets, not, I imagine, wishing to be caught out when things do not work out quite as they forecast.

The muddle-through-to-a-glorious-future approach has few supporters among economists. But simply muddling through, without the expectation of any glorious future, seems to be a currency shared by many among both economists and the wider population.

For me, and millions like me, opposition goes much deeper, and in the event of any kind of Brexit our opposition to a departure from the EU will remain as virulent as now, until such time as circumstances oblige us to re-establish the connection we have so rashly thrown overboard.

For reasons, as I see them, read on. Feel free to add, or subtract.

historical (1): fly solo at your peril, build don’t tear down alliances – never over-estimate your power or position in the world, or assume that past prestige guarantees future influence – never draw empty parallels, one example being the specious argument that the UK leaving the EU is a re-run of England versus Rome in the 1530s;

historical (2): the bond created over seventy years of peace and cooperation since World War Two isn’t one to be lightly set aside;

political: it may or may not be that, under Trump, a transactional, case-by-case approach to policy will work for the USA, but a smaller country, and the UK is a smaller country, holds few cards – self-interest not charity among partner countries will always prevail – negotiations involve unpalatable trade-offs, a blank slate is no place to start – always build from strong foundations, with plans in place for all eventualities – bluster is no substitute for hard graft;

economic: on what basis could we ever assume that the EU would agree that we can take out (i.e. trade) we do now, without putting back (financially and in other respects) at a level comparable to current levels? – that we can somehow reverse gravity theory and its thesis that our closest neighbours are our best and favoured trading partners? –  that the theory of comparative advantage, whereby we all specialise in those areas where we have advantages not shared by others, could ever deliver other than diminished returns and destruction of existing industries, not least because we would be inviting in tariff-free products from a world which is unlikely to reciprocate?;

philosophical: for many a vote for Brexit was simply a vote for change, a plague on all your houses, but change rarely delivers what we expect, and that applies especially to change as little planned and falsely argued as Brexit – the frequently peddled and spurious notion that there is some kind of a contract between government and governed, which begs the question of what’s in the contract, who wrote it, and who are the ‘people’ – how democracy functions is a fundamental question, see next item, and flawed concepts do not help;

democratic: decisions must be reversible, and are best handled by elected and representative assemblies, referenda being the favoured tool of those who wish to bribe and manipulate, or as happened in the Brexit vote promote a specious ‘free trade’ agenda on the back of hyped-up panic about immigration, that of itself an example of how a critical issue can be radically mis-represented;

humane: rules and regulations exist to protect the working population, not as some would have it for their own sake, and future trade deals will allow minimal change from what we have already have;

humanitarian: we are all citizens of the world, as well as the UK and Europe, by definition, a simple and to my mind ontological truth – what we can bring to the world, not how best we can hide behind borders, should be our focus, and we can drive that worldwide agenda far better through the EU;

environmental: as ‘humanitarian’ above, working together with people in other countries, pushing a climate change agenda, exercising influence on the US and China which we could never do on our own;

judicial: the rule of law must always be above politics, a notion that has been unwisely challenged in some quarters;

sovereignty: we have greater sovereignty as part of a wider body wielding influence in a US/China/EU dominated world, than a supposedly greater say on our own – ‘taking back control’ is a fiction whereby we lose much more than we gain;

demographic: where comes our uniqueness as a nation: from closed borders, from excluding foreigners? – the opposite has always been, and should always be, the case;

influence: why leave the forum through which are influence has been most effectively spread and felt around the world in recent times? – any more than we should leave the United Nations on the grounds of poor performance – we will effect change by working on the inside, rather than gesture politics on the outside;

reform: expanding on the idea of influence, there are vast issues out there in the world which British pragmatism and ingenuity can help solve, but we will do that as insiders, pulling levers, arguing in corners, never by grand-standing;

pragmatism: implicit in all the above, but worth separating out – pragmatism is what has always defined us as a nation, which is why so many beyond these shores are astonished to see so many in our land practising the politics of division – and badmouthing the institution with which they’re negotiating, and yet anticipating a happy outcome … curious indeed;

reputation: why be taken as fools, as we are being already, and risk being taken as greater fools, with our new friends the Republican right, the supporters of Marine Le Pen in France, Matteo Salvini in Italy….

The flag of St George turned into a jingoistic banner cannot be the way forward for this country (for sure, it can’t be for Scotland, or for Northern Ireland, and, despite a majority voting for Brexit, for the population of Wales). With sanity and pragmatism we can avoid fracture now, not least territorial. Without it the battle-lines will remain, and skirmishes and worse continue, for many years to come.
