This war between Russia and Ukraine is one in which a pragmatic leader could call to an end for the sake of his people. For Ukraine there's no further need for Zelensky to still trying to push hard, find ways out to talk with Vladimir Putin, not as a show of weakness but as a pragmatic leader.
I remember when Putin was interviewed by one of the journalists. He says that he is very easy to forgive, but the only thing he cannot forgive is betrayal. Putin felt that Zelensky betrayed them by joining NATO and ignoring the Minsk agreements and that was a fatal thing, because Zelensky indirectly invited NATO to the borders of Russia, which is their enemy. A meeting of the two leaders is necessary to resolve this issue and Ukraine should lower their egos for the good of their citizens.
