The juxtaposition of the two sections I've enlarged in bold is what is intolerable to me.
Killing and maiming so many, creating a huge refugee crisis and destroying so much infrastructure is inherent to that policy of fighting, totally unnecessary and not benefitting the whole of humanity.
Did all of the previous wars stop this one? No, and this one will not stop any future wars. There can be no benefit. Listen to the language of the Ukrainians now on what they are going to do to the Russians. They've sunk to the same level as the Russian behaviour, it's what war does to people.
Being a good neighbour seven years or more ago could have prevented any chance of this war, it should at least have been tried, instead of the idiotically aggressive language the Ukrainian president used then and is continuing to use.
Failing that working and Russian forces massing on the border years later should have been met by him taking the high moral ground with Putin with this message to him, made public worldwide:
"For many centuries we were first Russians, second Ukrainians. We are not in any way a threat to Russia and never intend to be since we are brothers, neighbours and would be friends.
As such we will refuse to fight you, so you do not need any forces or need to use any force to enter our country.
If you have a problem which Ukraine can help with, you only need to ask and we will do everything we reasonably can to help.
I look forward to meeting you."
That would give peace a chance. If it failed to get a mutual agreement and Ukraine capitulated with no fighting to unreasonable Russian demands, the West could still have taken all the same harsh punitive measures against Russia that it has taken now.
But that way there would be no deaths, no maiming, no wrecked infrastructure, no refugees. Just a wholly innocent nation of peaceful people made the victim of a ruthlessly unreasonable neigbour who is being duly punished long term.
That is the civilised way to deal with this issue.
