Likelihood of a German Invasion of Ireland during the winter months. 6. From the political angle a German attempt to invade Ireland in the immediate future seems improbable. Hitler and his advisers have hitherto shown a tendency to concentrate on doing one thing at a time. Enemy forces are now engaged in North Africa and in the Balkans, and the air attack on the United Kingdom continues. We think it unlikely that Hitler would decide to embark on a further adventure such as an invasion of Ireland, whilst these other operations are in progress.
