   • 2022 September 30, 3:10 from the start, in Ukraine makes NATO membership bid following Putin's annexation of four Ukrainian regions‎^[1], spoken by Volodymyr Zelenskyy, Al Jazeera:

     It is here within the state borders of Ukraine that we can confirm the strength of the borders of all European countries. We can guarantee that nobody will dare to return tyranny to our continent. It is here that the values of our Eur-Atlantic community have been revived by a people that is fighting for freedom and with other nations that help us in the struggle. We are real allies with NATO. We have covered this road to NATO. And in actual fact, we have proven that we are compatible with the standards of the alliance. They are real on the battlefield in every aspect of our cooperation. We trust one another, we help one another, and we are protecting, defending one another and that is our alliance. This is an actual alliance.

• Some usage guides prescribe “each other” for two entities and “one another” for more than two. This distinction is not observed in practice. The Oxford English Dictionary describes the pronoun as referring to “two or more”; Fowler’s suggests that the distinction “is neither of present utility nor based on historical usage”. The Merriam-Webster Dictionary of English Usage notes that “a few commentators believe the rule to be followed in ‘formal discourse’. This belief will not bear examination: Samuel Johnson’s discourse is perhaps the most formal that exists in English literature, and he has been cited in violation of the rule.”
