While there is a dedicated field of 'Political science' in place and studied across the world universities, why most of the policies in highest ranks are devoid of scientific characteristics? How the science could be of support of decisions made by politicians that for example, an exit of US from environmental pacts or the worse of all, starting wars across the world. Ironically, all the politicians have support of related political institutions in their country. So there is a so-called 'Science' that supports opposite leaders to go to a given war. What is the nature of this 'Science' that could lead to the human catastrophes that we are facing today? Could the political science behind the conflicts be considered a 'Science' by definition? If so how it could lead to opposite decisions in the price of people's lives and security as in a war?
