I don't get your comment?... prominent members from various versions of the IRA are and have been members of Irish governments, see Gerry Adams/Martin McGuinness (Or even Michael Collins if you're talking way back).
Whenever said members/affiliates are former leaders we're really just splitting hairs. I get your point though, I mistook what he had said as there is no link at all between them. Instead he is saying 'The Irish government never commanded the IRA' which I'd largely agree with.
