Was their international standing that high before?
State sponsored drug cheating. Poisoning people in the UK with radioactive weapons and nerve agents. Poisoning political opponents in Russia.
Backing the Syrian regime and corrupt dictators in Africa through Wagner.
Why would Russia care about it's standing in the West?
They are ruled by an oligarchy determined to keep their grip on power at all costs.
It's a win. You fight Russia, you pay a heavy price.
If Ukraine had been able to win the regime would have likely collapsed.
The Russian army was somewhat feared before the war.
It's true strength was an unknown entity, and has now been exposed as a busted flush.
Putin had years to plan and build up his forces. Yet corruption at the highest levels meant that his weapons/equipment just wasn't there.
I'm not sure who was more shocked him or us!
It has been a total embarrassment to Putin/Russia that it hasn't been able to take Ukraine.
Any expansion thoughts he may now have won't include any Nato or well armed country. This mainly thanks to the bravery and heroism of the Ukraine fighters.
I don't think he reckoned on the depth/reach of the sanctions, thinking his gas/oil reliance would keep the world quiet.
Basically, the long term cost to Russia/Russians would mean any victory now would be hollow anyway.
