But its still just a bigger axe, so the Soviets have a few really big ones and the Americans a lot of smaller ones, an axe is an axe it is no "final step in MAD" because MAD itself is a "final step". A couple thousand 'regular' nukes on both sides is all that is needed (as opposed to the tens of thousands made by both sides in the Cold War).
And the Earth has been impacted with FAR worse things than 1,000 MT of explosives, remember the Dinosaur extinction? That would make the 1,000 MT look like an M-80 next to a 100-pound bomb. And the American counter-strike will have far more explosive power in their combined total.
As for fallout, well with how many nukes we've detonated since 1945 in tests I'm not sure how much would be in the Soviet one.
But really, nothing changes, its still the same nuclear brinkmanship that worked so well in OTL, its just now the Soviets might NOT be capable of pulling back, not that they don't want to, but that they made their options so that they CAN'T.
Also, remember, its one thing to wipe out every human on earth, either in the barrage itself or the ensuing nuclear winter. Its quite another for ALL life on Earth to die off. If you'd looked at Earth 3 months after the asteroid that wiped out the dinosaurs hit you'd think nothing would have survived, but it did, something always will.
