I apologize for the very large volume. They washed over me in a heavy wave and covered my head with memories that couldn’t be summarized in two pages. But maybe someone will master them... And I want to say that I do not pretend to the depth of analytics. These are only personal impressions and opinions, my personal, and personal attempts to understand something. And I have no goal to humiliate any nationalities - all the negativity is only about criminals and idiots, and nationality is not the most important thing here...
