Who knows where he's going to stop. But at the moment, he's only taking what's owed to him. We can think of Putin as someone like Hitler, who really didn't want to stop til he took over all of Europe. So assuming Putin will be the same as Hitler, is a bit far fetched at the moment. I have reason to believe he will stop before getting to NATO countries. That would be WWIII. Put doesn't have the military to fight WWIII, without China, India & Iran backing him. And since he has no legit reason to take over Poland or Germany, then there's no reason for China, India or Iran to back him.
He just wants NATO to stop trying to put missiles in Ukraine. For Ukraine to pay him back. And for Ukraine to stop trying to mess with Russia's oil getting to Europe. Ukraine charging him $4 billion per year for Russian oil to flow through Russian pipelines (through Ukraine) is ridiculous. Especially after the decades of Russia helping Ukraine stay afloat.
And then there's that whole Donbas mess. IMO, Putin is just tired of Ukraine and their entitled attitude.
OWES HIM ?
The Ukrane has been raped & pillaged for centuries
You statement is like saying India has a debt to the UK for all the years of occupation .
If you check the set up in the USA you will find every state charges for pipelines that pass through them.
At one time every state charged tax on freight that flew over the state even if it never landed there.
I used to be required to generate better than 100 pages of various customs declariations to get stock from Sydney to NY
The way it works is Putin sends in trouble makers & stirrers who build up anti government sentiment
Then they start a movement to remove the government or find a reason why they should be an independent country.
Then insurgents get sent in to start a civil war
Then Russia moves in to protect the freedoms of the insurgents that they sent in originally.
They did this with Georgia and right now the Goergians are protesting their Russian puppet government
Similar thing is happening in Belurussia
Who owns what piece of real estate just depends on where you draw the base line
The Monguls owned the Ukrane
Turkey owned the Ukrane
The Ching Dynesty owned the Ukrane
The Tsar owned the Ukrane
the USSR owned the Ukrane
And I am sure there are more than what I know from my limited knowledge of European history .
And every one of them had different borders so it also depends upon what you consider the Ukrane actually is and who would be called a Ukranian .
America was a continent occupied by natives that belonged to a variety of nations .
No country ever became a country voluntarily
They all have their origins in conquest and a foreign person determining totally artificial borders .
The net result of that is perfectly reflected in the middle east which would be called bad at the best and a disaster at worst and most of the problems now have their roots in borders decided by a bunch of western generals post WWII for the benefit of their own countries, not the conquered natives .
