What was the resolution that began a bombing campaign in vietnam? a. domino theory resolution c. rolling thunder resolution b. tonkin gulf resolution d. johnson resolution

B. Tonkin Gulf Resolution
The Domino Theory is the idea that if one country falls to communism than a domino effect will occur and neighboring countries will become communist. This thought was a large player in causing the Vietnam War but it is not a resolution and it did not begin the bombing campaign. Operation Rolling Thunder is the name of the actual bombing campaign but it is also not a resolution. Lyndon B. Johnson was the President during that time and the one who carried out the bombing campaign but once again, Johnson was not a resolution. The Gulf of Tonkin Resolution was passed by Congress and authorized the use of the military in Vietnam, leading to the bombing campaign.
