Final answer:
The transition from the 1950s and 1960s to the era of Vietnam and Watergate had a significant impact on the public debate over the role of a strong president in democratic government.
Step-by-step explanation:
In the 1950s and 1960s, the United States went through a transition period with significant world events such as the Vietnam War and the Watergate scandal. These events had a profound impact on public debate over whether a 'strong' president is a threat or a support to democratic government.
The Vietnam War resulted in widespread anti-war protests and a growing opposition to President Nixon's policies. This led to a questioning of the role of a strong president in making decisions related to military conflicts and foreign policy.
The Watergate scandal, where President Nixon was involved in illegal activities, further deepened the public's distrust towards a strong president and raised concerns about the potential abuse of power.
