believe it or not, FEMA has had a plan in place since the 80s. they are going to call it NW1

because well no one was paying attention in the '80s The military intelligence and governments of all the superpowers realized they should rethink their strategy regarding nukes

So they stopped planning contingencies for global annihilation and started focusing on LIMITED NUCLEAR THEATER

That's exactly what they called it
"limited nuclear theater"
small tactical nukes

very survivable.. of course it will wipe out entire cities but it won't wipe out the entire world

It's actually quite manageable

And the scariest part is our military has already made contingency plans for how to deal with limited nuclear war and how to respond with limited theater as well

Like they decided "well we're willing to lose LA Chicago New York and Miami and Atlanta but at least we won't lose the entire country.............

NW1.... NUCLEAR WAR ONE
(of course that rolls out the red carpet for NW2 and eventually NW3)
