First of all, check out the actual letter. Don’t worry, it’s short—I count just 134 words in the body proper. Notice anything…strange? Well, I sure did. See, of those 134 words, Truman—at the height of World War II’s climactic, multi-front fever pitch, minutes before (and minutes after) his own sudden thrusting into the Presidency—spends 31 words—almost 25% of the whole letter—talking about Spott The Dog’s dietary habits. Look, Truman was a smart guy. Nothing was accidental. And so, I think I’ve uncovered an until-now secret player in the iconic 1945 Yalta negotiations.
