What were the most significant results of the cuban missile crisis?

The United States gained knowledge of the missile base being constructed in Cuba during a routine spy-plane surveillance.  President Kennedy immediately organized the EX-COMM team which was made of twelve of his most important advisers.  After seven days of debating what action to take, they performed a military quarantine, poised and ready to attack if needed.  They surrounded Cuba by air and sea, not allowing anyone or anything to go in or out.  Cuba shut down the missile base.
