Biden and Putin will always be enemies but must talk at some stage

There appears to be no turning back for Joe Biden and Vladimir Putin. Biden has now called Putin a war criminal and a butcher. When the war in Ukraine is over - and if the world has survived - Biden will be reluctant to ever ring/talk/meet or even say hello to Putin. On the face of it, the bad-mouthing has gone too far for the two leaders to ever consider being civil to each other again. Which is understandable because Putin is a monster who is killing women and children in Ukraine like he doesn't care. He thinks avoiding killing civilians - what the West calls colateral damage - is for whimps. But for the leaders of the two biggest nuclear powers to stop talking to each other is unfortunately bad news for the rest of us. At some point - it may be many months away - Putin will have to be spoken to. And not by Macron who has had endless conversations with the Russian so-called leader without getting anywhere. Biden speaks so gently and quietly I doubt Putin can even hear what he is saying. But in the future when Putin realises he has to at least acknowledge Biden's presence, the US president will have to speak up and more robustly than he has done so far. Putin needs to be put in his place but for the sake of world peace, Biden and Putin will have to talk. But right now the language has become so belligerent it seems unlikely Biden will want to sit down with Putin whatever eventually happens in Ukraine. But US presidents have sat down with butchers and war criminals before, and unless Putin is overthrown - an unlikely event - Biden will have to deal with this terrible man, nauseating though it might seem right now.
