I think my question was misunderstood.
Your original post makes it seem like you think NATO are the bad guys here because they are supplying weapons to Ukraine to defend themselves.
I asked "who attacked who" because to me, it seems pretty clear that Russia, a dictatorship whose government has a history of human rights violations and disregard for human life, is doing a bad thing when they invade a neighboring country and start shooting missiles at civilian homes on a daily basis for a year and half.
Could you explain how this is not a clear "Russia doing bad thing, we should help Ukraine" situation?
