USA and the UK are two different conglomerate of states in the world. USA, completely known as United States of America has a federal and constitutional republic form of government while the UK (United Kingdom) instills the constitutional monarchy-parliament governance. In this regard, the head of the state along with the representatives are elected into office by the people in the US. They do their roles as government officials under the code of an already set constitution.
Conversely, the UK has its monarch who acts as the head of state and absolute power is not vested unto this monarch because there is usually a duly elected separate head of the government that exercises political powers. These leaders, like in the US, uphold a set of laws in the form of a constitution. In terms of the number of states, the US is composed of fifty different states and a federal district (the seat of governance). The UK is a unitary or single state nation that is composed of four separate countries namely: Northern Ireland, England, Wales and Scotland.
Geographically speaking, the US is like a large continent with most of its states residing in the Northern American continent. UK, on the other hand, is an aggregate of small and big islands. Thus, it is more similar to an archipelago. The US has an obvious advantage of land size because it is dubbed as the third or fourth largest country with a total of 9. 83 million square kilometers of land. UK only has 244,820 square kilometers of land.
The US economy is obviously the number one and biggest sole national economy worldwide that reaches more than US $14 trillion of GDP while the UK is only placed at 6th place with over US $2 trillion. However, it must not be forgotten that UK was hailed as the first ever industrialized country in the world. It was even the most powerful country during the 19th century. But when the World Wars came to reality, its power slowly dwindled. Today, the US has become the most powerful nation in the world in terms of military strength and national defense. Summary: 1.
