Indonesia sets the perfect example for Turkey

President Recep Tayyip Erdo?an has two theses: The presidential system would uplift Turkey, as this is how developed countries are ruled, and there can also be a presidential system in unitary states. 

I don't know who is advising the president, recommending these ideas, but within G-20 countries, there is only Indonesia that is both a "unitary state" and ruled by the "presidential system." Well, Indonesia cannot be regarded as a "developed" country; its national income per capita is about one-fourth of ours. 

Among those G-20 members ruled by the presidential system, the Russian Federation is a federal republic ruled by a semi-presidential system. It has 85 federal units. The federation is made up of 21 autonomous republics that have their own constitutions, parliaments and presidents, 46 oblasts that have local legislative organs and presidents, krays, autonomous okurgs, one autonomous oblast and federal cities. 

South Africa is four-zonal federative republic. It has three separate capitals. Pretoria is the administrative capital, Cape Town is legislative and Bloemfontein is juridical. 

South Korea is ruled by a president; there is a strong separation of powers. Semi-autonomous "local governments" have their own legislative and executive organs. 

The United States of America is a federal state ruled by the presidential system. As its name implies its states are united. The states elect their governors and there are assemblies that process their own domestic laws.

Argentina is a federal republic containing 23 states and one federal region. Every state has its own assembly and an elected governor. 

Brazil is a federal republic with 26 states which all have (you have not heard this from me) their own flags...
