Only government is the one who wants more power while the citizens wants only a peaceful life.
NATO should accept Ukraine application and help to stop war instead of accepting country near the border since it will just provoke Russia to continue the aggression due to the expansion of NATO.

NATO accepting Ukraine directly is way riskier move then accepting other countries that have border with Russia. Because if Russia wouldn't back off or at least stop their actions right after that, it would be in direct open war with US and Europe.
And while accepting countries that have a border with Russia might seem like a provocation, it's about de-escalation. Without joining to NATO other border countries would be next. Because after invading country of 41 million citizens, would an idea of attacking Finland that has population of 5.5 million seem impossible for them? Even though Finland has build their and securing their supply chain since last war with USSR and has comprehensive conscription service.
Russia view NATO as threat to their goal as you said already that they want to reclaim the old USSR, They are just expanding until they both hit another country like Ukraine that both Russia and NATO have an interest for expansion. This is what I don’t understand on this expansion. Does their resources is already not enough to sustain their own citizen?
But you shouldn't really even compare NATO and Russia expanding themselves. Russia is expanding by invading countries that don't want in. And raping and killing kids while doing that and submitting those invaded under a dictatorship.
