Thanks for the information. I shall bookmark this.
There is a lot more that I found - you can just Google "Alger Hiss United Nations". Hiss was at Yalta to make sure that Stalin got what he wanted there which was control of Eastern Europe. Later Hiss was in SF to ensure that Stalin got what he wanted vis a vis the UN. And Hiss was a proven Soviet Spy. And as the info above indicates, there were a lot more spies than just Hiss. John Kerry isn't the first traitor in the US govt, just the latest!
