Did the governments of the US and European countries attempt to negotiate with Russia prior to the invasion of Ukraine?
I am aware that the US began warning other countries regarding the military buildup on the Ukrainian border in November of last year, and that the Russian Government denied that they were going to attack until it actually happened.
But prior to the military buildup it seems that most countries were aware of a potential escalation in conflict, and I was wondering if there is any evidence of attempts to negotiate with Russia to prevent an attack.
Any sources would be greatly appreciated.
