I see nothing wrong with S21.
Cambodians may interpret S21 as something bad, but this is
Singapore, not Cambodia.
Singaporeans don't see anything bad or sinister about S21.
Ironically, Singapore aided the Khmer Rouge communists against
Vietnamese communists during cold war. Paradoxically, the Malayan
communists were in a war with Malaysia and Singapore too, with
their base in southern Thailand.
Mr Lee estimated that Singapore spent about US$55
million; Malaysia about US$10 million and
Thailand a few million, in
training, food and ammunition funnelled to the
insurgents, he said in his memoirs, From
Third World to First: The Singapore Story 1965-2000.
