Re: War? Nope
I hope you read your own contracts more carefully than that, because an exclusion for "hostile or warlike action in time of peace or war" by a "government or sovereign power" doesn't require an actual state of war to exist. And BTW, Mondelez is the customer, not the weasly insurance company.
Having said that, I still don't think Zurich has much hope of avoiding paying out. More likely the aim is doing a quick out of court deal to lower the quantum.
