The only way out of this war is Zelensky gives up some territory. He can then argue he has saved most of Ukraine while Putin can claim victory.
A fight to the death will mean the war goes on forever and many more lives will be lost.
We are living in a world that is in the land of the fairies. We have Trump claiming the Nobel Peace Prize when all he does is start wars. We all know that Trump is evil and only thinks about himself.
As for the Iraq war this will only end when the USA has completely destroyed that country as they did with Iran. Alternatively there will be a cease fire when the US stock market collapses in style and the billionaires intervene.
As for the World Cup, I doubt it will go ahead. You cannot run a World Cup in a country at war.
