There is no true democratic presidential system, and even the US model has problems. Every country should switch to a modified semi-presidential system. The president should announce laws according to law and issue orders, and the prime minister and relevant ministerial deputies should be appointed and countersignature. The prime minister should act on the basis of public opinion and command the government and national defense. See the Charter for Permanent Peace for details. §1.4 §6.4 §7.3 §8.3
