Saudi Arabia

Saudi Arabia is an absolute monarchy governed by the Al Saud royal family. The King holds legislative, executive and judicial authority, chairs the Council of Ministers and serves as head of state and government. There is no elected national legislature — the Consultative Assembly is appointed and can only advise. The legal system is based on Islamic (Sharia) law, and the King's power is constrained mainly by religious authorities and consensus within the royal family.

United States

The United States has a presidential system with a strict separation of powers between three co-equal branches. The President is uniquely both head of state and head of government, elected separately from the legislature via the Electoral College. Congress writes the laws and controls spending; the President executes them and can veto legislation; the Supreme Court interprets the constitution. This system of checks and balances means power is deliberately divided — the President cannot dissolve Congress, and Congress can impeach the President.
