Every point you mentioned is just parroting the Russian narrative.
There's no such thing as "good trade relationships with Russia", as those that were there existed only thanks to planted agents like Gerhard Schröder.
What most likely triggered this war was Putin's ambition to stay in power, as Russia never actually recovered from the 2008 crisis, so he let Medvedev handle the popularity hit associated with the first years post that.
Russian agents are sabotaging European businesses as we speak - there's no getting back to whatever level of friendly relations there were before the invasion.
Gerhard Schröder was no planted agent, he acted out of a belief in what he did. The german left have always had a strong connection to russia.
I live in northeast Germany and the cost of living increase and industrial cost of the nord stream & oil pipeline changeover has been immense.
I am not advocating a "friendly" relationship w russia but it's also wrong to over simplify the relationships. The nord stream sabotage was a HUGE gut punch for former east german states.
And yet NATO expands most readily when Russia invades another country. I wonder why nations might want in that alliance? You're just repeating Russia's justifications for their actions, which have never made sense.
NATO expansion was because countries begged to become members of NATO, out of fear of Russia invading them. The only reason Russia minds NATO expansion is that it prevents them from starting easy wars.
