Lets look on it dispassionately while others rant.....
Those who deserted a countrys army are Court martialled irrespective of who they fought for............. don't remember Allied govts having a sympathethic view of any who deserted their side in WW2 and fought on German side.
I notice the OP uses the word "Alledged" in looking at desertion, its pretty black and white really, you either did or didn't.
Happy to be proven wrong but we didn't treat deserters in WW2 well, seem to remember the Cossacks, Soldiers and Civilians getting handed over for execution by the USSR.
The banishment from public employment for a period of 7 years is not a surprise given the taxpayers don't wish to fund people who have fought for another state in a war. Over here UK public bodies acted similarly against Conscientious Objectors who were dismissed by councils and private employers so there is consistency of treatment as much as we don't wish to believe it.
The locking up of Children in what was called "Industrial schools" is and will always be an abonimation but given many children were abandoned in a poor country which had bugger all there was not a lot of options. We sent them to the colonies in the 40's / 50's and 60's, stealing them from their parents but seems we started this in sending "Vagrant children" to the Virginia colonies in 1618 and continued this practice up to 1967 in sending to Australia. What is our excuse ?
As a somewhat student of Irish history I would be wary of attempting to see this through 21st Century eyes......
Given Ireland had Independence for 17 years when WW2 started and an economic war in 1930's had impoverished an already poor country then it is not surprising the stance taken by the Govt of the day. UK didn't exactly part on good terms so why would be expect anything to have changed in 1939 ?
Reality is they were neutral in our favour and supplied us with lots of food that we needed. The overwhelming majority of the people in Irish elections voted for parties that supported that neutrality. So can't on one hand say we fighting for democracy and then abuse those who decide democratically what is best for them.
Irish Free State made its position clear at start of the war and maintained it even when it could have gained in joining in at last minute like quite a few countries. They kept that neutral position and somehow think the hiding of links between our Govt and Irish Free state are more to do with how much they assisted us after all Irish state has nothing to lose post war in what UK issues from its records has it ?
DeValera gave his condolences to German legation on death of leader of Germany but he also did exactly the same at the US embassy on the death of President Roosevelt ensuring he acted impartially irrespective of the abuse he knew he would receive.
