The Irish loved the Nazis during WWII, that's why they were neutral. They wanted to see the Nazis marching into London.
The “neutral” bit had to do with not wanting to get punished militarily if they openly backed the Nazis and Britain won.
When Britain was in its darkest hour and it was threatened with starvation by the U Boat campaign, Dela refused to allow them to use the former British naval bases on the west coast to station anti-sub patrols. It would have reduced the Mid-Atlantic gap greatly.
