1 Soldier Ishmael: So you Martians, being from Mars and all, probably don't know about the war, right?
1 Young Adam: War?
2 Soldier Ishmael: Yeah. World War II. It just ended.
2 Young Adam: Oh, that war! We er... know a little.
3 Soldier Ishmael: Shame about Nazi science developing the atom bomb first.
3 Young Adam: Yeah... wait, what?!
4 Soldier Ishmael: But now we have it too, it's a standoff. Sort of a "cold war".
4 Young Jamie: Oh, this is so not good.

"Atom bomb" is such a cute name. It's a shame this 1940s and 50s term fell out of favour for the more boring "nuclear bomb".
