What Trump overlooked in his presentation was the reality that the liberation of Europe began long before the D-Day landings. And the burden had almost exclusively been born by the Soviets.
It would be good if both sides calmed down and stopped claiming either that D-Day won the war or that it was a very minor offstage event. But that’s probably too much to hope for today.
The USSR, with significant help from the rest of us, defeated Hitler and changed the world away from that dark and horrible future. At enormous cost.
The problem isn’t that Truman often misunderstood, but that he surrounded himself with people that his Party’s top donors liked. Truman wanted to be a progressive but ended up being only a liberal.
