President Lyndon B. Johnson, Address at Johns Hopkins University: "Peace Without Conquest," April 7, 1965:
"We are there because we have a promise to keep. Since 1954 every American President has offered support to the people of South Vietnam. We have helped to build, and we have defended. Thus, over many years, we have made a national pledge to help South Vietnam defend its independence. And I intend to keep our promise. To dishonor that pledge, to abandon this small and brave nation to its enemies, and to the terror that must follow, would be an unforgivable wrong. We are also there to strengthen world order. Around the globe, from Berlin to Thailand, are people whose well-being rests, in part, on the belief that they can count on us if they are attacked. To leave Vietnam to its fate would shake the confidence of all these people in the value of an American commitment."
Which of the following historical developments during the late 1960s or 1970s represented the most direct departure from the foreign policy assumptions expressed in the excerpt?

- CThe decision to limit the application of the containment doctrine to European nations to prevent direct conflict with the Soviet Union
- DThe launch of the Tet Offensive, which served as the primary legal authorization for the escalation of U.S. forces in South Vietnam
