Question

which best describes why the government tried to prevent the new york times from publishing articles on the vietnam war?
the articles praised the presidents actions.
the articles criticized the military.
the articles threatened national security.
the articles supported communists.

Explanation:

This refers to the Pentagon Papers case. The U.S. government argued that publishing the classified documents (which detailed the government's misleading of the public about the Vietnam War) would harm national security by revealing sensitive military and diplomatic information. The other options are incorrect: the articles were critical of presidential actions, not praising; while they were critical of the war effort, the government's formal legal argument centered on national security, not just military criticism; the articles did not support communists.

Answer:

The articles threatened national security.
