Huntington's Actors

Huntington's clash of civilisation is one of the scores of theory, that want to or atleast try to predict the unpredictable? As many are saying ,he seems to be reductionist. Definition of culture hasn't settled yet. there exist lot of overlap between religion or culture or any other unifying forces. Is there clear cut demarcation between cultures? Huntingon know that there is no such thing. can this demarcation emerge in due course of time?. Yes this can happen. When Marx proposed his theory, people laughed at him. Socialism, communism never existed as separate entity but humanity created it, influenced it, polarised it. Difference does exist today as existed from centuries. 18 th century Europe used some difference to create nationalism and concept of nation state, if same notion were to be used then Indian subcontinent would have had many nations. But it didnt , so then can we say that theory of nation state is faulty; no we cant. Over generalisation or over stretching can be disastrous. can we ignore it (nation theory); no we cant. super slav state balkanised into 9 state. point is we as player fail to recognised our own bias; we take theorist at their face value. Although huntington has failed to describe players involved in it. inter civilisational clashes and alignment effect and many such things. He has left people to discover possible solution or resolution etc. Actor of clash of civilisation are very important; he has given that credit to whole community which may not be fare. However i want to ask other here ; Is ISIS or IS one of the actor of Clash of Civilisation.
