Crazy thought, suppose you were able to go back in time and change just one event in history what would it be?
It was tempting for me to say stop Diarmait Mac Murchada asking for King Henry II's help in regaining his kingdom which would eventually lead to the 800 year English conquest of Ireland, stop Lee Harvey Oswald from assassinating JFK or stop the Ulster Plantation from happening but I chose stopping the death of Michael Collins.
The trajectory of Irish history was no doubt greatly changed by his death. I think he could have been Taoiseach. He might have got a peaceful settlement from the Civil War which might have saved lives and possibly united Sinn Féin meaning we wouldn't have had the civil war politics we currently have today or he could have led the pro treaty Sinn Féin side with more focus on the democratic programme which the Cumann na nGaedhael government largely neglected or maybe his leadership wouldn't seen Fianna Fáil largely dominate Free State/Republic of Ireland politics. We may not have had De Valera as Taoiseach with his protectionism that destroyed the country and took years for it to recover.
