"There is nothing in the article to support that assertion."
Read the article and read the rest of his articles (as I now have - those on line anyway)
His whole work is dedicated to how the ideals of Easter Week have been betrayed by what has happened to the Republic since - as is Tim Pat Coogan's book.
His criticism of Coogan was not on what he had to say but on what he regarded as shoddy workmanship on dates and note-keeping, as were the criticisms of the other three historians - as amatuish as Coogan can be at times on technicalities, he remains one of the most respected historians in Ireland - though you can never know that as you have bnever read anything of substance on Ireland and you have said you have no interest in doing so - who are we to contradict you?   
You really have not got your head around the fact that, unless you read the writings of the historians you persist in hiding behind enough to understand what they are actually saying, they will continue to blow up in your face, as has Kineally, Max Hastings and now Ferriter..... and virtually every other historian you have used in this way
"Please remind us what was the "credible evidence has been presented here that there were significant shortcomings in the Home Rule."
Home Rule kept Ireland within the Empire while historically, Ireland wanted Independence - it was signed on the basis that Ireland would be partitioned temporarily, but was made invalid, even to its loyal Irish supporters, by Britain secretly altering it to permanent partition.
Britain tore up the signed agreement and replaced it with one bulldozed through by the Northern Unionists.
What problem do you have with this Keith - is it wrong - have I made it up - did this not happen - what?
You have had credible evidence in the form of Lloyd George's confessions that it had been done - what more "credible evidence" do you need other than that?
