So politics have to be separated from morality? Politicians are supposed to make decisions for the best of the people, the national interests you talk about are for people, and people are guided by morals and social norms. You can't talk nonsense and try to cover it with "from a political point of view". It is so ambiguous and only sounds stupid. So in this information generation you do not need the pleasure of brain stimulation and satisfying encounters through experiencing new people and new places every once in a while? If you think that travelling to a new place is the same as reading about that place in your smart phone then I have nothing further to say.
