The germs got us. Cut big stretches through the U.S. We were just lucky. The germs played out in a couple of months, while we were holed up. Soviets said they'd used the bio stuff in amongst the nukes to show us what they could do, long term. Unless the war stopped right there. Which it did.
But enough nukes blew off here and in Russia to freeze up everybody for July and August, set off those storms.
Germs did the most damage, though-plagues.
It was a plague canister that hit the Slocum building. That did in Mobile.
The war was all over in a couple of hours. The satellite people, they saw it all.
Now they're settling the peace.
