True, but dollars can be converted into ICBM interceptor missiles.

ICBM interceptor missiles are far more expensive and less reliable than warheads.

Nuclear hot war is unlikely.

It is far less unlikely than it is was month ago

And I'm about to get shot by dog with a handgun[0]. Of course nuclear is a concern to be aware of -- but that is why NATO et. al. aren't responding with boots on the ground. In our current situation, where that has been unequivocally ruled out by the NATO leadership, the risk is still tiny, and we have plenty of other more pressing systemic risks to deal with first.
