From the Powerline archives:

Obama’s historical howlers: Obama has repeatedly made it clear when invoking American history to support his positions that he is shockingly ignorant. In support of his advocacy of presidential negotiations with Iran, for example, Obama points to the constructive role that the Kennedy-Khrushchev summit in Vienna played in the ultimate American victory in the Cold War.

By all accounts, however, the Vienna summit was a disaster for the United States. It led, among other things, to the emplacement of the Berlin Wall by the Soviet Union, to the Cuban missile crisis and to the enhancement of the American role in Vietnam. Either Obama is familiar with the history and is deliberately exploiting the ignorance of his supporters, or he has no idea what he is talking about. (I incline to the latter view.)
