Edit: You are misleading everyone here in this forum. Please read third paragraph
Then You will find why he emigrated to Sri Lanka. There are good and bad things in every country. He enjoyed his late life in Sri Lanka with rich culture and amazing climate.
What you are saying the reason behind Arthur C Clarke emigrated to Sri Lanka was wrong. He emigrated to Sri Lanka in 1956 mainly to scuba diving.You did not mention references related to that period.
