Not to sound ignorant

[Burney]

You would describe the Cuban missile crisis as Kennedy coming close to tipping the world into nuclear war?

You could make a pretty strong argument that he did very well to stop it from happening.

In response to a nuclear threat to US territory, he chose to escalate the situation to the brink of nuclear war. That he may have been right to do so and the fact that we got back from that brink don't alter that fact.
My point is that nobody calls him mad for those actions.
