The linked article is about a backpack nuke. My comment was responding to the possibility of a terrorist group smuggling a tactical nuke or dirty bomb into the country. I was correcting some common misconceptions about such a scenario. I was obviously not talking about a nuclear exchange with China involving DF-5A ICBMs.
Fair enough!
Even North Korea's tests have run into the hundreds of kilotons.
Nobody's shooting Chicago to wound. If a nuclear missile hits us, we're not rebuilding.
