MacAskill is fast becoming the voice of a growing 'tendency' within the SNP that has turned to questioning the SNP leadership because all the questions that might be asked of the British state and its apparatus are now rhetorical.
There is not now and never was any route to the restoration of Scotland's Independence which does not involve confrontation with the British state. It was always a nonsense to suppose that, in the wake of the 2014 referendum and with a rising wave of democratic dissent in Scotland, there could ever be a viable process that was critically dependent on the full and honest cooperation of the British government.
Wherever democracy is denied then there you find oppression however well it may be disguised. The Union was designed for the purpose of subjugating Scotland's people and it continues to serve that purpose well. Because we allow it.
I have little hope that the Yes movement is capable of turning itself into the kind of political force that would be required to 'persuade' the parties to accept the Manifesto for Independence.
I like to think of this as a Manifesto for Independence. Something quite separate and isolated from a party manifesto. A Manifesto for Independence to which any party or candidate might sign up regardless of their own policy platform or political agenda.
