I did get the feeling that you wished things were other than as they are.Not true at all.
The Irish tricolour was in use before the creation of the Free State in 1922, as was the Irish national anthem Amhrán na bhFiann. Both of these were subsequently adopted by the Free State however they were both belonging to the 32-County Irish Republic which was proclaimed in 1916, and which had a functioning Parliament, Army, Police Force and Courts for several years. It also had foreign embassies.
The national flag and national anthem are not the property of the 26-County state, and the 32-County Irish Republic was never disestablished.
Err.... no:None of this is terribly relevant to an electrical forum, but you brought it up.
Because it's not the flag of a foreign country. It is the national flag of Ireland, which has 32 counties.
However much you wish that were so, however much you wish that the 32-County Irish Republic which was proclaimed in 1916 still existed, the fact is that it is not and it does not.
