And yet those are the policies that Irish are supposed to put their faith in to justify not aspiring to anything more ambitious than Home Rule, rather than treating them with as much cynicism as English voters apparently did.
And as for the First World War, it puts the implementation and acceptance of Home Rule on a clock, which is part of the problem. Actually, my biggest problem with your argument at this point is that it's amorphous and impossible to construct into a coherent narrative. Home Rule is passed when? The Ulster Volunteers are dealt with how? The British army? They don't mutiny like they did at Curragh why? During the war, there's no Conscription Crisis why? And Labour surges to overtake and destroy local Irish parties whose descendants still exist in Northern Ireland now, despite being stigmatized by the Catholic Church. When, exactly, and how?
It's just hard to engage with an argument that's this shapeless, and that seems to account for butterflies only when doing so is convenient. I mean, the fact that I've spent this much time unsure of whether your scenarios featured a World War should tell you how fundamentally confusing your case is.
