This is like saying, “that is not a dog, it is a Labrador retriever.” In other words, just nonsense.
I would love you to tell people in France or Korea that they don’t live in democracies. It would just be funny to see how stupid would correctly guess you are.
France is a Republic within a semi-presidential system (President and Prime Minister).
Although both France and the United States are representative democratic republics, there are important differences between their political systems. In the U.S., the executive power is held by a president, while in France it is shared between a directly elected president and a prime minister elected by the legislature. In France the lower legislative chamber, the National Assembly, is more powerful than the Senate, while the American legislative chambers have roughly equal powers.
