My neighbor's tree crushed my fence. He says it's not his problem

A storm came through recently. My neighbor’s big spruce tree and already looking rough with cracked branches and a slight lean and finally gave up… And it fell right onto my fence... Took out about 6 panels

I had noticed this for months and tried to tell him about this. He did not take it seriously then. Now he is shrugging his shoulders and says that it is an act of nature and not his fault at all. And I am left with a fence down and a large tree in my backyard

I found out that in our county, there is a rule that depends on the state of the tree before falling. If it was obvious that it was dead or damaged in some way, the owner must have taken care of it. But how do I show this?

Should I call an arborist for an inspection? Someone who can look at what’s left and give a professional opinion? And I’m also thinking about calling tree removal services to get the tree cleared. But who pays for that? Me? Him? Insurance?

I’m annoyed and honestly not sure what to do next. I don’t want to start a war with my neighbor, but I also don’t think I should be stuck paying for something I warned him about

Has anyone dealt with this before? How did you handle it? I could really use some advice before I make things worse
