The Portuguese manager was installed at the Serie A giants in 2008, and has been involved in numerous disputes with Italian journalists ever since.
Mourinho assured that no matter how hard he was criticized, he would never 'lose his personality'.
"From the day I left Chelsea I said that I would go back to England and that has not changed," he said.
"A few days ago I said I'd remain at Inter until 2012, which is the end of my contract, but the truth is people only like to highlight certain statements.
"It's true that I will return to England one day, I am sure of it, but I don’t know if it'll be 2012 or 2020. I am happy in Milan.
"I'd never criticize Italy as a country or its people, but I was referring to the rapport with the Italian journalists that is not positive. In fact, I'd call it a war.
"In my view the situation is your fault, while you think it's down to me. The fact remains it is a war I cannot win because you are many and I am on my own.
"I can lose a war, but never my personality, my independence or my freedom of thought. I will never be an ****-licker. I'll always stay independent and say what I think, even if many don't like it."
