Political homework: Why do the British, American and French have the same style, but different regimes?

Because, in addition to being determined by the state system, geographical environment, historical origin, cultural tradition, population quality and social development degree are all factors that affect the form of state management. Therefore, although the United States, Britain and France have the same state system, they have different regimes. The state system determines the regime, and it is reflected through a certain regime. The regime embodies the national system and serves the specific national system. In order to safeguard the fundamental interests of the ruling class, we always strive to adopt the most effective form of political organization.
