S Artesian - agree with lots of that, the actual history of Bolshevism is much at odds with the standard interpretation of WITBD and the relation of party and class is not one of externality or unilateral dictation.
Jacob - I haven't read Lars Lih's Lenin Rediscovered yet, only some of his shorter writings. Is on my to do list though! I'm interested to see how his re-translation of WITBD compares to other versions.
Proletarian - dead briefly (and probably poorly), Marx argued for support for Irish national independence on a few grounds. Firstly, he argued independence would lead to the expropriation of absentee English landlords and thereby seriously weaken the British ruling class. Secondly, he argued that British imperialism had impoverished Ireland and led to mass emigration to Britain. Desperate Irish immigrants could be compelled to undercut "native" labour, driving down wages and contributing to an emnity towards the Irish. Thirdly, the separation of Ireland and Britain would undermine nationalist consciousness amongst British workers - he talks somewhere of Ireland being the lever to set the British working class in motion.
There is a section on the MIA collecting Marx's writing on Ireland if you want to read further...
