I have a pet conjecture that they might have actually murdered FDR too, though he was so frail that it probably only took a 'pat on the back' in Yalta [4] (unlike their first try on Navalny [2] and Yushchenko [3].) Unlucky for them, Truman ended up being a much tougher rival than FDR would have been, IMO.
