"The Greatest Generation", no doubt.
I recently had a weekend-long seminar on Operation Overlord and the Normandy offensive. It's amazing what went right, what went wrong, and what advantages luck and good fortune provided. A lot of lessons were learned during this period that shaped the future of the American military forces, as well as how we interact on an allied level with other international forces.
There's a lot of movies being remade these days. If it's gotta happen, I would like to see "The Longest Day" modernized with an all-star ensemble cast (as it was in its time) and staying true to the original.
