Eisenhower created NASA.
By create I mean really pushed for it. There was no sense of urgency until he spoke about putting the man on the moon. The program in the late 50s was very haphazard, and accomplished little.

JFK screwed up the Bay of Pigs invasion and also caused the Cuban Missile Crisis by foolishly placing American missiles in Turkey and provoking the U.S.S.R., causing them to place missiles in Cuba in exchange. Also, JFK threatened to place sanctions on Israel (an American ally) for building nuclear weapons even though its enemies were threatening to destroy it and "throw all the Jews into the Mediterranean Sea." In contrast, JFK allowed the U.S.S.R. and China to build and have nukes.
And yes, I know the Cuban Missile Crisis beginning was mostly the fault of JFK, but he managed to avert disaster once it began. Notably, much of the issue was taking the advice of his military advisors and going through with the Bay of Pigs. His ability got noticeably better after that.
You also seem to imply that JFK really had control over the internal workings of China and the USSR. I believe that he was justified to keep nukes out of Israeli hands- they should not have them even today.
