I was fascinated by Douglas Alexander's approach on Question Time last week. Not so much his demeanour and behaviour (as someone born just down the road, I always thought Bishopton boys were brought up to behave much better than that), but more the substance of his comments.
Mr Alexander's first line of argument revolved around the question: do we really want to break up the nation that defeated fascism together? He was referring, of course, to the Second World War. We owe the most enormous debt to those men and women who sacrificed their lives to protect this country. In many ways we owe them everything. Like Douglas Alexander, I was not around to experience the horror, the fear, the heartbreak, the courage or the indomitable spirit of those who lived through the war, I simply heard the stories second hand. But what I do know, intuitively, is that the Second World War should never be used as the basis for political point scoring.
Men and women who believed in the Union and in independence fought and died together.
Nations around the world united to stand up to the fascist threat, including some newly independent of Britain and some not. Even when Britain 'stood alone', the reality is that we stood shoulder to shoulder with, and fought alongside, people from New Zealand, Australia, the West Indies, South Africa, Canada, Newfoundland and India to name just a few.
And, have no doubt, an independent Scotland and an independent England would unite to fight fascism, or a similar threat, today, just as Scots, Welsh, English, Irish (including many from the south), Australians, Canadians, New Zealanders, South Africans and more did 70 years ago. You didn't have to be one country to fight fascism 70 years ago and you don't have to be one country to fight for what is right today.
The political point I will make is not about the past, it is about the future. In years to come, being independent will give Scotland the choice to fight with others, once again, in a just war, like WW II, and allow us to keep our young men and women out of an illegal war, like Iraq.
Mr Alexander's second argument followed on closely from his first: do we really want to break up the nation that, after the war, built up the NHS and the welfare state? 60 years ago the London government was building these things up, with the full support and participation of Scotland. Now, they are knocking them down.
And this is not a sudden or new direction of travel. For 30 years the choice of Westminster politicians has been to move further and further away from the social democratic founding ethos of our welfare state. This may make uncomfortable reading for Scottish Labour supporters, but they know in their hearts it is true: not even 13 years of a (New) Labour government reversed the trend, it didn't even halt it.
The country being fashioned by London governments is not the one we "built together" after the war. Devolution has allowed us to save our NHS from Tory plans to dismantle the service down south. Independence (or indeed devo-max) will allow us to save the rest of our social democratic society. And it is a society and a consensus, here in Scotland, that is under grave threat. If you doubt this, just read the Spartacus report to see what is being done, in our name, yes, in our name too, to some of the most vulnerable people in our country.
The "what we built together" argument harks back to a Britain that no longer exists. Nostalgia, as an anti-independence weapon, will back-fire spectacularly. Because, once the warm glow dissipates, the cold reality of today and the future comes crashing in.
Yes, we fought a just war together and would do the same again, but we don't want any part of Westminster's illegal foreign adventures and horrific weapons of mass destruction.
Yes, together we built the NHS, the state pension, the welfare state, but today, the NHS is on the way out in England as Tories build on Tony Blair's 'reforms'. And does anyone seriously believe the state pension or the welfare net are safe in David Cameron's hands?
Douglas Alexander is one of Labour's top thinkers, but by asking Scots to look to the past he serves only to highlight the many ways Britain is no longer the same country. The post-war Union 'deal' has changed - against the will of the Scottish people expressed in election after election. The pace has stepped up, once again, under the Tories, but have no doubt the terms of the partnership have been altered by successive Westminster governments.
If we want to protect and preserve the things we hold dear, the things that reflect our values and our priorities, then independence is the answer.
If we see the contract we thought we had signed together, changing beyond recognition, is it not time to look for a new deal? To replace the old Union we have today with a more modern relationship that works for both nations as we move forward together in this 21st century?
Let London, if they choose, spend precious billions on new nuclear bombs rather than those same billions on better childcare or decent pensions. But not in our name. Instead, let the people of Scotland, the people who care most about Scotland, choose a better way. Let us learn from the past, and build for the future with independence.
