For normal explosives, you're spot on. While the explosives do
generate a certain amount of gas of their own, it rarefies *very*
rapidly when there's no atmosphere for the blast wave to propagate into.
For nukes, you've got a radiation wave that will do Nasty Things to
whatever it hits... but nukes tend to be tricky to set off even on
purpose; they're far harder still to set off by accident :-/
