Michael Collins was never sendt to England to talk with the British government, in fact it was Arthur Griffith with Collins merely as an deputy.(The question and answer beneath seems to be based on the 1996 movie "Michael Collins" by Neil Jordan, not actual historical events.)After Collins and de Valera's army had settled down with the British, Michael Collins was sent to England to settle the terms de Valera and himself wanted for Ireland. The reason that is thought to be for Collins going instead of de Valera is because de Valera in fact knew that he would not be able to free all of Ireland but a portion. So de Valera used Collins as a scape goat so the Irish people would hate Collins for not freeing all of Ireland not de Valera.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
