This would have been around the same time as The Duke and Duchess of Windsor, Lord Rothermere via his Daily Mail and a great many British public figures and politicians were lending their support to Herr Hitler (I seem to remember that Oswald Mosely had a knighthood conferred on him - correct me if I'm wrong). When the news of the extermination of the Jews reached Britain one Tory Minister described it "the invention of whingeing Yids".
None of this, of course, has anything to do with the present situation, neither does the pragmatic and very wrong "my enemy's enemy is my friend" - so what's your point?
Interesting that your information came from Ireland's leading history Journal though.
Now about your proposal for invading the North.....
