That’s not even the main point of the video. The White House had every opportunity to avoid this war. He said they had multiple concerns.. Yet virtually no attempt was made.
There are multiple reasons, not just Nato. Primary is no US involvement.. especially after the coup of 2014 (this ties with no Nato) and the Donbas situation - thousands of civilians killed there since 2014.
Apparently Ukraine and Russia had an agreement in March for neutrality and an independent Donbas. That agreement would have been just fine. However Zelensky was convinced otherwise thru offers of more money and weapons, billions flowing into Ukraine. Ukraine has always been considered pretty corrupt and easily manipulated.
Bottom line, Russia will never allow the US to have primary influence in Ukraine uncontested. That’s why there needs to be an agreement. Eastern Ukraine and Crimea are not like any other former Soviet regions. The Baltics states have always hated Russians. Billions have flowed into Ukraine from the US since 2014.
