Final answer:
The Moral Majority and similar groups in the 1980s would have likely supported increased defense spending as part of their conservative ideology, aligning with policies that advocated for strong military funding and national defense during the Cold War.
Step-by-step explanation:
The position on defense spending advocated by the Moral Majority and similar conservative groups during the 1980s would have most likely aligned with support for increased military funding and a strong national defense posture. These groups, which emerged in part as a reaction to the social and political changes of the 1960s and 1970s, often supported the policies of President Ronald Reagan who championed an aggressive defense policy against the Soviet Union during the Cold War. This stance reflected their broader conservative ideology which included a strong anti-communist sentiment, support for military strength, and the idea that a robust national defense was essential to maintaining American values and interests.
