Why was monolithic soviet communism an important idea for the reason why US supported Diem's regime in south vietnam from 1954-64? Give 4 reasons.

I already have some but i just want some more ideas for brainstorming.

To understand why the US supported Diem's regime in South Vietnam from 1954-1964, it is important to consider the broader context of the Cold War and the ideological rivalry between the United States and the Soviet Union. Monolithic Soviet communism, as an important idea at the time, can be linked to the US support for Diem's regime based on several factors:

1. Domino Theory: The US subscribed to the Domino Theory, which posited that if one country fell to communism, neighboring countries would follow suit in a domino effect. As a result, the US viewed South Vietnam as a crucial domino that needed to be protected from the spread of communism. Monolithic Soviet communism, with its central control and adherence to the Soviet ideology, reinforced the fears of a global communist expansion, compelling the US to support Diem's regime.

2. Containment Policy: The US pursued a strategy of containment to prevent the spread of communism. Monolithic Soviet communism represented a unified and centralized communist system that the US aimed to contain. By supporting Diem's regime in South Vietnam, the US saw it as an ally in stopping the spread of communism and an opportunity to counter Soviet influence in the region.

3. Fear of Soviet influence: Monolithic Soviet communism represented the Soviet Union's aspiration to expand its sphere of influence. The US was concerned about the growing Soviet presence in Southeast Asia and saw supporting Diem's regime as a means of countering Soviet influence and preventing a communist takeover. By supporting Diem, the US hoped to establish a non-communist stronghold in South Vietnam as a bulwark against Soviet expansion.

4. Ideological Alignment: Monolithic Soviet communism stood in stark contrast to the US's capitalist, democratic values. The US saw an ideological kinship with Diem's regime, which aligned with their vision of an anti-communist, pro-Western state. Supporting Diem was seen as a way to promote American values and protect their interests in Southeast Asia in the face of Soviet communism.

It is important to note that these reasons are not exhaustive, but they provide some additional ideas to further explore the complexities and motivations behind the US support for Diem's regime in South Vietnam during this period.
