Failing to defeat your enemies in combat but managing to kill literally everything else including everyone in your homeland too with fallout isn't a very convincing victory. We can do that already, we just don't for obvious reasons.

Especially when gundam already has space colonies. They already got the "leave the polluted earth behind" solution ready. It's a big problem in AC because their colonies are in atmosphere. Even in the absolute worst case scenario where every next becomes a dirty bomb and the entire planet is scoured clean of life, half their population doesn't even live on the planet.

Zeon pretty much tries to do this every few years already. It'd suck but it's certainly not the end of the world. lol
