The correct answer is "firm and cautious".
The Cuban missile crisis was the most critical point of the Cold War between the United States and the Soviet Union. It occurred from October 16th to October 28th in 1962.
During these days, President Kennedy decided to execute a naval blockade on Cuba to prevent more Soviet missiles to reach the island and demanded the dismantling of the ones that were already located there.
After days of negotiations, the Soviet Union agreed to dismantle the missiles in Cuba and the United States agreed to dismantle its missiles in Turkey.
