Genuine historical question, is there any chance that the IRA could have succeed in creating a unified 32 county Irish state after 1955? Where they really anywhere near powerful enough for this?
Also the British government had several 'doomsday' plans for Northern Ireland, mainly involving the resurrection of dominion status for the region, as well as just outright abandonment, handing the place over to the UN and repartition. How would these plans come into effect? and what would that do to Britain, Ireland and the Cold War?
