We have the same problem. Prior to 2003, there was no memorial in France; there was nothing to commemorate.
How the Juno Beach Centre was conceived was conceived is the following. I was on a tour to commemorate the 50th anniversary of D-day, and we had three bus loads of veterans who went to Courseulles-sur-Mer, Beny-sur-Mer, and Bernières-sur-Mer—which is specifically where my father landed—and there was nothing there. The Winnipeg Rifles maybe had a small monument, but there was no focal point.
This group of veterans came home from that 50th anniversary and said that they had to do something. Garth Webb was the spearhead of this whole program. He began fundraising but hit roadblock after roadblock. He went to Canadian companies such as the Royal Bank and Molson's, the typical big Canadian companies, looking for funding. It was only with Walmart, which was looking for a Canadian cause.... It was the right time at the right place, and they took us on board and helped us fundraise. They never really gave us any money.
I think to answer your question, it would take the same kind of impassioned veterans group for Korea to do the same thing.
