Somebody ought to have thought that one through, sitting there in the middle of WWII with the lights on. The USAF even managed to bomb Switzerland, and so many planes landed on Swedish lakes that the Swedes complained they were running out of storage room.
The same reason de Valera signed the Book of Condolence at the German Embassy on the death of Hitler, the same reason Irish Volunteers in the Allied Forces were imprisoned, banned from the Civil Service and many other jobs, banned from state aid, and their children vilified at school by teachers in state sponsored hatred, on their return from the War, because de Valera was a self serving traitor to the Irish People.
The Big Fella had him summed up, before de Valera had him murdered, as more interested in power than the people, more interested in himself than Ireland.
Ireland was a neutral country but whilst the lights burned it enabled the Luftwaffe to find it's way across the Irish Sea to bomb Liverpool with its large Irish population!
The Irish Republic actually deviated slightly from strict neutrality in the UK's favour - German aircrew were always interned (although it was a fairly soft regime, where they were allowed to go out to the pub).
For British aircrew near the border there was a lot of blind eye turning as they made their way over to UK territory.
When Belfast was bombed the Irish premier said it was the quickest political decision he ever made to send fire appliances to help the Authorities (technically a breach of neutrality) and the firemen were cheered to the echo by every town and village they went through on the way to the border.
nope radio dublin transmitting on a constant frequency aided herman's boys more. they only needed radio hamburg to get a perfect triangulation.
mind you they were well within their rights to do so, being neutral, and some may argue they didn't owe us anything, i guess aiding by proxy a regime that industrialised mass murder might have given them a bit of a shock when the full extent of it was exposed.
They didnt specially turn them on. As they were neutral they were not at war with Germany and did not expect being bombed. They did not turn any on for sinister reasons.
Remember there were lots of Irish people fighting with His Majestys British forces.
Wii? Nintendos didn't exist back then.
