Anyone who watched even a small portion of today's ceremonies and still can't fathom or "get" the significance of Vimy clearly has very little appreciation for contemporary Canadian History.
Listening to the words of the Canadian veterans and in particular the words of the thousands of Canadian high school students visiting the memorial at Vimy and watching their emotions as they began to understand the power of that place, was both heart warming and gratifying as they began to understand the sacrifices that people - not much older than they are now - made at that time and place in defence of this nation.
The US Civil War? Really? Why should I care beyond pure historical curiosity: that is for Americans to ponder and dwell upon.
As a Canadian Vimy is an infinitely more powerful and seminal event and a symbol of youthful sacrifice; whether it was as critical to creating a sense of a more independent Canada is a matter for debate, however if you still don't "get" it after today's moving ceremonies, I suspect you never will understand the true impact its significant insofar as this country is concerned. Fortunately many others do.
