Because of the history of Ireland and the complexity of their relationship to UK. It is true that there were deals with Nazi Germany, and it is well documented. I wouldn't judge all the Irish people for this, because like all things there were many others in Ireland who would have been appalled at making any kind of deal with the likes of Hitler.
Sorry for the Irish people in general but they wouldn't own up to any kind of complicity, because I am sure that many would be ashamed to find their past relations in anyway in league with Nazi Germany, but as said there is plenty of evidence to support this. It may not have been the alliance that you are referring to but there were plenty of Irish sympathisers to the Nazi cause. Apologies for copying this but you did ask for info Collaboration between the IRA and Abwehr during World War II ranged in intensity during the period 1937 - 1943 and ended permanently around 1944.
The Irish Republican Army (IRA), a paramilitary body active in Ireland, seeking an end to partition and British influence on the island, shared intelligence with the Abwehr, the intelligence service of Nazi Germany. As to Fred, perhaps he should read up about Irish history, St Patrick wasn't an Irishman born and bred, but Romano/British, and sadly many of the Irish were complicit in the truly appalling Irish Potato famine, landowners were not all English you know, many were Irish and cleared the people off the land, so they could put sheep and cattle on, making more money, than having poor peasant on it, as I said deplorable, but its time that some people read their own history before banging on about the English.
Ireland was neutral. However according to the conventions of war, any ship or submarine from a warring country entering a neutral harbour was supposed to be prohibited to leave the port and it is widely rumoured that Ireland did not abide by this convention. I think Brazil was also guilty of allowing German ships to be repaired in Brazilian harbours and then being permitted to go out to sea.
There were other 'neutral' countries which did not comply with the conventions. It has been widely reported, that if allied soldiers or airmen turned up in Switzerland, they were interned, whereas wounded Germans were treated in Swiss hospitals were returned to Germany once they were healthy again. These are, of course, rumours.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
