I think the statement regarding the Soviet Union's use of simulation cities needs a citation. – The preceding unsigned comment was added by 174.108.11.91 (talk • contribs).

The citation is VOY: "In the Flesh" which it states in the article. The line from the episode itself goes:

PARIS: Back in the twentieth century the Soviets used to build American towns to train their agents to infiltrate the United States. Species 8472 could be doing the same thing.
