This book is a worthy book that I've bought. Nattapoll Chaiching is one of the famous Thai political historians who provides a lot of information and evidence about the U.S.A role in Thai politics (1947-1957). Sometimes the U.S.A supports the military coup and sometimes they support the royalist and Thai army to fight against Pibulsongkram, Pridi, and Pao for their benefits in Thailand.
