That reminds me of a Doonesbury cartoon from the early 1970's. Viet Cong soldier Phred, who had befriended long-time Doonesbury character BD, decides to take a vacation from the war. He takes all his money to the airport and asks at the counter where he can go on that much money. The clerk tells him "Cambodia." So he goes to Cambodia and takes tours of ancient temples. He asks the Cambodians he meets about the "secret bombing of Cambodia" by US planes in 1969. They all tell him "Secret? What secret? The planes come, the bombs fall, BOOM! Everybody knew about it! Weren't no secret."
