Answer:
c) The united states shot down soviet spy planes in the caribbean
Step-by-step explanation:
An American U-2 WAS shot down over CUBA by a Soviet-manufactured SAM rocket and the pilot murdered, not over the USSR. An American U-2 DID interfere with Soviet airspace, off base on an air-testing mission, yet Soviet contenders were requested NOT to flame on it-simply send it home. When Kennedy made a deal to avoid attacking Cuba amid the emergency or a short time later if the rockets were expelled under UN supervision, relations would ease, yet the danger would stay until the Cold War was authoritatively pronounced over.
