This isn't like Norway and it's even less likely to work than Sea Lion. Whilst the Irish Army is rather weak, the Germans are going to have the joys of no supplies and no naval support, if they can land in the first place.
And if they, somehow, manage to capture a few key cities (lets say they manage to take a line running from Cork to Dublin, and an enclave in Limerick), the chances of supplying them when Ireland will surely turn to Britain at this point for aid in sorting out a blockade (or even simply a blockade instituted unilaterally) is practically nill. And that's not withstanding the fact that you may see Britain sending some volunteer units from the Irish population in the country to help liberate Ireland without sending in the army and risking endagering the locals.
Funny thing is, this might in the long run turn out much better for Northern Ireland.
The one extremely remote possibility (and we are really close to ASB here, maybe in ASB) would be if the rabidly anti-British Eire PM Eamon de Valera's government conspired to allow it and presented the UK with a fiat accompli.
Actually a rather plausible pro-Axis Ireland would be if the Blueshirts took over in a March on Dublin, which De Valera feared would happen. If they did and took over then who knows what Eoin O'Duffy may do as leader of Ireland, seeing as he believed himself to be the "third most important man in Europe" after Hitler and Mussolini he may get a bit too cocky and attempt war with Britain, maybe get resources from Germany in the 6 years between the March on Dublin and start of World War Two? Or he might actually be sensible and merely act like Spain.The one extremely remote possibility (and we are really close to ASB here, maybe in ASB) would be if the rabidly anti-British Eire PM Eamon de Valera's government conspired to allow it and presented the UK with a fiat accompli.
