The Irish Free State gave no help to the UK to fight the Nazis, although some Irishmen decided to join the fight as a personal decision.
Great Britain, or more correctly The United Kingdom of Great Britain and Northern Ireland, was involved in both World War 1 and World War 2.
Northern Ireland was part of Great Britain in WW2.
Ireland was still a part of Britain at the time ... On 5 August 1914 Britain declared war on Germany on behalf of the entire British Empire.
A number of bombs were dropped in Ireland in World War II, but it is believed that these were as a result of pilots mistakenly thinking they were over Britain. Ireland and Britain are very close to each other.
American Soldiers came to Britain in World War II to help out.
Ireland wants independence.
Ireland took the view that it should remain neutral as it was not going to side with Germany but would not support Britain. Britain needed bases in Ireland to help in the war against the U boats. Ireland would not supply these bases despite the fact that goods imprted to Ireland came on exactly the same ships needed to supply Britain. Nontheless Ireland maintained its Neutrality.
