NATO chooses to invite members, or not.
Russia asked to join. They were refused.
Because NATO is an anti Russian alliance.
It is exists solely to contain Russia. It has no other purpose.
Ukraine and NATO had to know that pushing Ukrainian membership would lead to war,sooner or later. It's not about right or wrong, it's just the way it is. The Russians have been crystal clear about that since 2007.
Ukraine killing Russians in the Donbass was causing tensions, it's not really too hard to figure that out.
If they were prepared to accept the consequences, the Ukrainians were just doing their own thing,as horrible as it was. The consequences were shooting war.
The Russians made their position very clear. Unlike the West, They didn't lie about their intentions.
The West was perfectly happy with provoking Russia. They knew Ukraine was not a member of NATO. They knew that when it came to the wire,they didn't have to actually put soldiers on the line. That would be Ukrainian people dying only.
The West got to test advanced weapons systems against Russia,with no loss of Western lives.
I long ago concluded that this was their real intention.
Give the Ukrainian people the false belief that NATO membership was just around the corner,coming soon.
Then cynically feed the resulting war with modern western weapons to fight proxy war with Russia. The best part is Russia stupidly started the war themselves, you can't make this up. It's evil off the charts.
Knowingly provoke a shooting war by tricking Ukraine into believing they would get membership into an alliance that they would no more be accepted by than Russia was. Certainly not in the short term.
Both Ukraine and Russia got played. Ukraine worst of all.
