Those of us who support disarmament long for a day when politicians end the perpetual arms race and focus on issues closer to home. Trident itself is part of a political mindset that says Britain should be playing an aggressive and interventionist role abroad.
Oh, I know what you're thinking. Have I got the right person? The geeky, awkward-looking politician who spent an unfortunate number of years behind some very unforgiving, ardour-shrivelling spectacles? Really? Oh, yes, I'm deadly serious.
Without first establishing that the old ways of thinking were misconceived, new approaches cannot be brought in to take their place. Yet the evidence so far does not suggest that Miliband's Labour is willing to take even this crucial first step.
Ed Miliband has been on the up. That's not saying much of course, because the starting point was that the public thought of him as a brother-knifing, out-of-touch geek who was largely incompetent (except at knifing his brother, that is).
Getting rid of Cameron could be the shot in the arm that the blue team need, especially against an opposition that has the public ear after last year but has yet to summon up widespread enthusiasm for its own vision of where Britain should be headed.
Since the recession, spending has shot up. But this just makes clearer that it's economic failure that leads to rising overall benefit bills - and not Labour's decision to tackle child and pensioner poverty.
'One Nation' is about moving beyond artificial divisions in society to build a better Britain where everyone plays their part and everyone receives a fair share. But the problem with that is it sounds lovely, but is also a little bit meaningless.
Were Cameron to commit to a referendum he would unleash years of uncertainty about Britain’s future place in the world. And that could undermine the very reassurance, and reputation for moderation, that will be central to the Tories’ prospects of victory in 2015.
