I want to know the answer to the following question:
Which US President prevented Turkey from invading Cyprus?
All the background I'm provided with is that "Meanwhile, by 1964, enosis was a Greek policy that could not be abandoned; Makarios and the Greek prime minister Georgios Papandreou agreed that enosis should be the ultimate aim and King Constantine wished Cyprus "a speedy union with the mother country".". Is that enough to answer the question?
