> Nuclear weapons need to be dismantled or stored in neutral territory in case we encounter belligerent aliens.

Lifeforms able to travel the universe are unlikely to be vulnerable to our nuclear weapons in a significant way. They might just not care about us and eat our sun. Or they might infect our planet with their spores.

The idea that space-faring aliens would be at a comparable technological development to our species has no base. That we would have a chance to respond to an attack is even more remote. It just makes for a story we can respond to emotionally, which is why these stories are told. Hoarding nuclear weapons for for such an occasion would be like goat-sacrifices to the gods.
