I'm sorry for your losses. War is ugly and to be honest, war is mostly fought by deception. I concede that a Russian act of Terrorism is a likely a plausible root of this action. Always look for reason, though, and not just obvious finger pointing. For example: if the reasons don't fit, consider the deception standpoint. How better to gain support for Ukraine forces than to commit an act that you can say Russia did? Not saying this is the truth, just saying. War is ugly and is best served through deception. Despite my viewpoint presented, I am truly sorry for your losses.
