Baloch are NOT ethnic

realised some Baloch and non-Baloch use a wrong terminology ' ethnic' or 'ethnicity' about the Baloch in Iran or Pakistan. The Baloch people are indigenous native inhabitants of Balochistan, under the political geography of Iran, Pakistan and Afghanistan. As such, they can be described as a nation, not an ethnic group in any of these three countries.
Therefore, I see no problem in referring them as 'the Baloch nation' in Iran, Pakistan or Afghanistan. Likewise, one may use the terminology of 'nationality' about the Baloch in each of these political entities. For example, one may use the term 'Baloch Nation' when talking about Baloch people in general.
However, one may argue that the Baloch are not a 'nation' as they have not their own politically independent modern state. Although, I appreciate their argument, I believe that in today's 'post-modern' age - if I am allowed to use this concept- the use of 'nation' or 'nations' cannot be limited within formal political entities.
Obviously and quite rightly, many commentators use the term 'nationality'. For example, one may say that there are different 'nationalities' in Iran such as Kurds, Persian, Baloch, Turkmen, etc.
The main mistake/ concern is the use of 'ethnic groups' or 'minority ethnics' when we refer to the Baloch or any other nationality within their own land. As I understand it, 'ethnic groups' or 'minority ethnics' can only be used about people who are not native to a land/ country in recent historical sense. For examples, the 'Indian Mohajers' who migrated to 'West Pakistan' after Indian partition are an ethnic group.
The Armenian people in Iran are an ethnic group, as they were initially brought to Persia during Safavid dynasty. The German people in Russia- who were sent to different parts of Soviet Union during Stalin's rule- can be described as German ethnic group in Russia (Although Both German and Armenian are 'proper' nations in Germany and Armenia).
As far as the Baloch are concerned, they are not an 'ethnic group' in Balochistan. The Baloch are native people in the land of Balochistan, whether it is in Iran, "Pakistan" or Afghanistan. The concept of Baloch migrants is another issue. The Baloch in India (new post 1947 Hindustan), Arab countries, Africa, Europe, Americas, ... are indeed 'ethnic groups' within those countries. There is no American or European or Arab or Indian Balochistan, whereas we have Balochistan within Iran, Pakistan or Afghanistan.
There are nations/ nationalities of Scots, Welsh, English and Irish in Britain. There is a Basque nationality in Spain. There are Kashmiri, Punjabi, Bengali, ... nationalities in India. There are nationalities such as Pakhtuns, Tajik, Turkmen, Baloch, ... in Afghanistan. No one refers to the Welsh or Scots as 'ethnic groups' in Britain. They are 'nations' within Britain. However, 'Indians' or 'Jamaican' and other people (apart from English, Welsh, Scots, Irish) are referred to as 'ethnic groups' or 'minority ethnics' or 'ethnic minorities'.
In short, the Baloch are NOT ethnic groups in Pakistan, Iran or Afghanistan. There is a Baloch nationality in Iran, Afghanistan or Pakistan. As far as 'national question' is concerned, I'll leave it to politicians who are more qualified to answer it. My main concerns are the issues of 'concepts', names, literary and cultural terminologies.
