Of course he was born in Hawaii.
Have you ever looked at where Hawaii is on a globe? It's farther from foreign countries than even the American mainland. The idea that his heavily pregnant mother (flying is not at all fun for pregnant women) would get on an early 707 and fly at great expense to some foreign country is ridiculous — especially the popular theory that he was born in Kenya. Do you know how many different flights she would have had to take to get to Kenya in 1961? Honolulu to California, California to the East Cost, the East Coast (refueling at Gandar Bay) to London, London to maybe Cairo, Cairo to Nairobi. How much would that have cost? And then you would be stuck having your baby in Africa rather than in a modern American hospital in Honolulu.
Or you could go the other way around the world — it's about the same distance either way. Kenya and Hawaii are more or less on the opposite sides of the globe, almost as far apart as two places can be.
This is a very silly idea.
