This is a super interesting read about people back in the 60s (...it was written in 1967, so they're contemporaries) who were already poring over documents, convinced there was a conspiracy to kill Kennedy.
Indonesia would be completely different. JFK was planning to meet with Sukarno shortly before he was assassinated. Then we got Suharto, New Order, the rest is history (over 1,000,000 communists, atheists, feminists, etc killed, and the third world is set back).
