In books and interviews, Noam Chomsky recalls that during the Vietnam War a diorama of a Vietnamese village was built at the Chicago Museum of Science where "children were supposed to come and play, and shoot at the village with the guns".
There was in item in the New York Times that described an event that took place in Chicago. The Chicago Museum of Science, which is a very respectable place, had put up an exhibit. The exhibit was a Vietnamese village, sort of a diorama of a Vietnamese village, and around it there were guns, and children were supposed to come an play, and shoot at the village with the guns. That was the game.

or see this interview with Chomsky on Youtube.
It also reports that the New York Times published an article criticising a group of mothermothers protesting outside the museum. However, I can not find any other sources that confirms the facts. Is Noam Chomsky's version of the events accurate?
