This thesis of yours has a weak connection to the concept of "patriotism," especially when applied to other countries, for example.
But in my opinion, you can substitute any country there, and it will still make sense. I substituted mine, and I got a satisfactory result that corresponds to observations of the local political course.
And isn't it just my country that can be used? Substitute the United States, Great Britain, Germany...
And secondly, this is not my thesis, but that of the methodological group for the history textbook.
Знание некоторых закономерностей освобождает от изучения многих фактов.
Мечты сбываются рано или поздно, так или иначе.
