Answer:
Cuban Missile Crisis.
Step-by-step explanation:
Cuba, which was an ally of the USSR that is located off the shores of the United States, was receiving shipments of Nuclear-armed Missiles, which were in range of several US installments and shipments. The US ran surveillance as well as a blockade in an effort to keep the ballistic missiles from entering Cuba.
The event was resolved when the USSR agreed to remove the ballistic missiles, in which they in turn asked the US to remove theirs from Turkey. The settlement was made, and crisis was averted.
