What type of government is involved in decision-making that impacts the entire country?

The answer is national government because it has the authority and responsibility to make decisions that have far-reaching effects on the entire country. This includes developing national policies, implementing laws, managing foreign affairs, and regulating commerce and immigration. The national government operates at the highest level and is responsible for addressing issues that affect citizens across all states and regions, such as national security, education standards, and healthcare regulations.

In contrast, local governments primarily focus on community-specific issues like zoning, local law enforcement, and local education systems. State governments handle matters that apply to their particular state, including state laws and regulations, but these decisions do not impact every individual in the country as a whole. Regional governments, though they may represent collective interests within a part of the country, also do not hold the same comprehensive authority or responsibility as the national government. Thus, when considering which government level is engaged in decision-making that impacts the entire country, the national government is the clear choice.
