My statement shows facts. A political entity would be the people and the government agree that its one nation. And one nation means that there is one political power that is over others within the country. And that even if there are political changes, either through election or revolution, its accepted that the country remain the same. For example, if someone overthrow the government of India, they would create a new government from the previous one. And if someone else also claim to be the legitimate government of India, then the country of India is now in a civil war. When Maratha take over land from Mughals, it was a war between two government that try to take over the land of another. Maratha leader wage war against Mughals, Hyderabad and Mysore, but they never claim that the rulers of these other places are illegitimate governments and only Maratha can rightfully be the government of India. But today, if the head minister of Tamil or Punjab wage war against the union government, it would not be a war among nations, but a war within a nation.
