Final answer:
The Smith Act targeted groups aiming to overthrow the government as part of Cold War-era measures.
Explanation:
The Smith Act targeted groups that wanted to overthrow the government. This act, officially known as the Alien Registration Act, was passed in 1940 and made it a criminal offense to advocate the violent overthrow of the government or to be a member of a group with that objective.
It was mainly used against Communist Party members and leaders who were accused of conspiring to overthrow the U.S. government. The act was part of the government's efforts to combat perceived internal threats during the Cold War era.
Other measures such as the HUAC investigations and the Taft-Hartley Act also targeted individuals and groups suspected of having Communist affiliations or sympathies.
