Best post-WW2 Secretary of State?

Best, George C. Marshall (Truman)
The Marshall Plan alone could reach this level, but he also understood cold war dynamics.  He was possibly the greatest post war Secretary of State, and was in the top ten in the history of the office.

Runners up were:

James Baker (Bush Sr.)     He basically oversaw the transition from cold war to the more collective approach, and the building of coalition in the first Gulf War was nothing less than brilliant.  He's possibly in the top ten as well.

Henry Kissenger (Nixon, Ford)  The opening of China, and his shuttle diplomacy regarding Israel were both brilliant.

James F Byrnes (Truman) Probably the most underrated.  He formulated the initial stand against the Soviets after WWII (unfortunately, he needed a dressing down by Truman to take that stand).

So you really honestly believe if Carter was reelected the United States would today be a commnist country under Soviet rule?

No, but I believe much more of the planet would be, both in terms of land area and in terms of percentage of the population.
