And you are absolutely correct: yes, the word Cossack - is a national name of one country and one nation, but it's not Ukraine or Russia. Word Cossack - is a national and historical name of Kazakhstan (Qazaqstan). In the original, the name of Kazakhstan is "KazaKstan" - that is, the word "stan" is preceded by the word "Kazak" - but today Kazakhstan has the letter "H(KH)" instead of the letter "K". I heard a story that Stalin wanted Kazakhs and Cossacks to have a different names, so it will be much easier to tell the differences between warrior group and entire nation, therefore he decided to replace one letter in the name of the entire nation. Today, Kazakhstan is trying to correct this "Soviet legacy" by replacing the letter "H" with the letter "K" (or "Q"), but people from Russia, of whom there are many in Kazakhstan, are very stubborn and do not want to accept any changes, even in one single letter, and in general they say that this is a stupid idea, because they don't like it. And this is not even a problem, but the real problem is that Russians even accuse neighboring countries of Nazism or "betrayal" because of such seemingly small decisions. Russians believe that everyone is "owe" to them and they have the right to everything. Therefore, decisions about any changes, even in a neighboring state, must be made in the bloody Kremlin. (This is their imperial past and complexes about the loss of the empire.)
