So it is only black and white with you?
Really?
And the whole situation is a helluva lot more complex than just 100% this or 100% that.
There are two problem makers here, not just one.
You take Sweden. Sweden has been a neutral country since 1834. I would expect that you know why that is important. I forget the percentages, but I think it is something like 80% of the population of Russia lives along the Swedish border. So Sweden being a buffer zone between one side from the other has been HUGELY beneficial for the whole world.
Ukraine should be neutral. Neutrality deals have prevented many wars over the course of humanity.
Russia was never going to accept a condition of Ukraine being a NATO nation.
And the value of Ukraine being a NATO nation, other than ego, is not worth the extreme high cost of making that happen. And that should be VERY obvious now.
But that is not what happened is it?
American interest in Ukraine kept escalating and escalating and enriching some high class folks. Gee, I sure know one of them don't you?
That was playing with fire. Actions have consequences.
Now... obviously Russia has some faults here too. They were also creating conflict. And both sides kept goading the other. What should have happened was making Ukraine a neutral nation. That it could cooperate and take any non military cooperation it wanted from either side as long as it wasn't military. And both sides agree to never take up arms against Ukraine, and Ukraine agree to never accept any military assistance from either side.
