Wait, I thought it was Kennedy's poor judgement that "led directly to the Cuban Missile Crisis" by placing nukes on the USSR border?

The US had had ballistic missiles (Redstone) in European airbases since 1958 -- Kennedy simply continued the existing policy of the US. Kennedy's poor judgment, arguably, consisted in aggressively defending the "rule" that it is acceptable for the US to have nuclear missiles near the Soviet border, but it is not acceptable for the USSR to have nuclear missiles near the US border. While JFK was driven by the need to appear tough, one has to give him credit for not following the advice of the "hawks" (Curtis LeMay) who advocated a preemptive invasion of Cuba, a move that would have almost certainly led to a nuclear exchange, given that the USSR had already placed (unbeknownst to the US intelligence) tactical nuclear weapons in Cuba.

I don't mean to suggest that Castro was the only person who showed poor judgement. Placing Jupiter missiles in Turkey ratcheted up tensions and invited some kind of response from the USSR - it increased the chance of nuclear war to some degree and it's fair to criticize Kennedy for that. But it wasn't a step-change in the perceived balance of power. Given all the possible Soviet responses, I don't think it was reasonable for Kennedy to conclude that placing missiles in Turkey would lead to a 50-50 chance of nuclear war.

I wonder if your parent has an answer to this. It seems the US putting weapons in threatening positions to other countries would be justified somehow.
