Are u Russian bot
I am not.
The war is going to end the way you think it is.
Early days Ukraine was going to negotiate the Crimea away, promise to end the provocation yo Russia, and agree not to join NATO. This would have been best.
The US instead wanted Ukraine to bog Russia down into a long drawn out war to try and hurt them. This is obviously at the expense of Ukraine, who have no hope of winning. Zelensky went with this instead.
At this rate it won't be long until Ukraine is demilitarised. They will not be able to threaten Russia for decades to come (potentially even longer if the war continues).
