You already, or should do, know about the negotiations which Zelenskiy was apparently in favour of pursuing. Unfortunately, he allowed himself, perhaps due to political immaturity and inexperience, to be outmaneouvred by nationalistic hardliners in the regime he unexpectedly found himself heading up.
No perfect outcome would have resulted from the negotiations, but the again, nothing is ever perfect, and peace, however imperfect, is always better than the hell of war.
But the hardliners in the Ukrainian regime have gained the most imperfect of outcomes. They do care deeply about 'their peope' though.
