I really enjoy Chinese culture and I find the Chinese people for the most part absolutely astounding, sadly our governments play us against one another. If all political nonsense and greed were to be set aside, which countries do you think would be best friends, or even allied together, based on their people alone?
Countries are countries, not people, and cannot really be friends. Countries, today, are all nation-states and therefore inextricable from the global caoitalist system, so to be free of politics would be to end every country. In this context, countries can be allies, usually due to shared interests to meet strategic goals.
Inversely, countries are enemies due to their inherent political nature, the global unstable system of exploitation. To imagine an end to inter-country hostility is to imagine the end of capitalism and nation-states themselves. Under such events the people who live in what is now Chile could love those in Saudi Arabia as much as those in Tanzania.
