It could be said to be dependent on which generation is looking at the tv reports but it's more complex than that. Those of us who were taught history know that Admiral Lord Horatio Nelson was the JFK or the John Lennon of his day. He was a brilliant naval strategist of his time and he was revered by those who served under him and adored by the British public.
Mankind lost a lot when they lost men such as him.
The conditions which gave rise to World War 2 came about largely as a result of the social and economic situation in central Europe after World War 1.
I am of the generation who knew relatives who had fought in the trenches of the Great War and our fathers and uncles had served in the Second World War so the collective memory of these world changing events resonated very strongly within our lives. The trenches claimed the very best men of their generation, those that mankind could least afford to lose. There are memorials in towns and villages all over Great Britain which commemorate the dead of both European wars, very few families were untouched by war and in British towns and cities aerial attack claimed the lives of service personnel but mainly civilians from within our close communities.
The horrors of conflict on this truly global scale coupled with the loss of innocence bought about by genocide cost mankind dear.
John F Kennedy represented hope for the post war generation, he was a remarkable figure for his time, a world statesman who bravely faced down the might of the Soviet Union during the Cuban missile crisis. Regarded by many Americans as being of immigrant stock and in spite of this elected as a Democrat in an ultra conservative nation just after the McCarthy era of communist scares and witch hunts one of his well known utterances was "There are no white or coloured markers in the graveyards of battle". He had begun to break down barriers and mankind was robbed of a great leader who would have cast off the chains and shackles binding predjudiced minds had he not been claimed by Lee Harvey Oswalds bullets at Dealy Plaza on that fateful November day. It was a loss that the world could ill afford.
John Ono Lennon helped to alter the perceptions of many of those of his generation. He taught those who would listen that there is no glory in war, peace is precious. He taught himself (and us) to respect women and to treat them as equals even though at the time he was reviled and laughed at for what he did. He opened the minds of many of us and his death was a loss to mankind. Who knows what he might have gone on to achieve in terms of influencing the minds of those with the power to change things?
Wars are being fought by our troops in our names now, today, and lives are being lost in a conflict that the Chief of the General Staff admits that we have no hope of winning. Can we afford to lose these young lives?
As Winston Churchill once said, we should learn from history, the lessons are there for all of us, including the young who disrespect memorials commemorating the sacrifice of those who allowed them to have the freedom to do just that.
There is no method of prioritising any of the deaths mentioned, from times which are beyond our memory to the present day we all lost something when every single one of them died.
