Aami states the following in their car insurance policy disclosure statement:
You are not covered under any section of this policy for damage, loss, cost or legal liability that is caused by or arises from or involves:
Radioactivity/nuclear materials:
action of nuclear fission including detonation of any nuclear device or nuclear weapon;
Why do they bother to delineate on the fission/fusion point?
Given that Russia's arsenal seems to consist largely of Fusion (Hydrogen) bombs, do you think I'll be OK?
I'm guess no, as they'd just state that it's an act of war, and therefore all bets are off anyway as far as they are concerned.
No if it is specifically written in.
