>Nuclear weapons need to be dismantled or stored in neutral territory in case we encounter belligerent aliens. If they've traveled across the stars to find us, I suspect nukes ain't going to save the day.

If they've managed travel from star to star, I very much doubt[1] there's anything of ours they want or need that they cannot make for themselves. [1] https://one.mikro2nd.net/2021/07/interstellar/ https://one.mikro2nd.net/2021/07/interstellar/

  Also, any civilization capable of harnessing the amount of energy needed for interstellar travel would have long ago destroyed themselves if they hadn't outgrown violent competition over resources. (The likelihood that few or no societies do so is the most likely answer to the Fermi paradox, and is strongly suggested by our own historical trajectory — see TFA.)

    Not necessarily. I think a belligerent alien civilization might be frequently warring amongst themselves, driving various factions to flee their planet/system/local group. If transport and hiding were easier than seeking out and killing those factions, such a civilization would spread quickly, driven by their belligerence.

If you replace inter-stellar with inter-continental, that might just be something that a (misguided) Aztec wise man would say when he met Cortez.

We cannot put our nukes to use beyond say the lunar orbit at the most. They can throw a few cheap but far more deadly rocks at us from the Oort cloud. Just being in a higher orbit with respect to the earth's is totally sufficient advantage for devastating destruction.

  With sufficient access to energy, I imagine you could do Rods from God at significant fractions of c from Alpha Centauri and give Earth a serious bad time. Planetary orbits are kind of regular after all.

    That is the plot of some Larry Niven Scifi :)

It reminds me of a part in The Dark Forest [1] by Liu Cixin, where a single alien probes annihilates a whole fleet of human space ships because of such big technology difference. This series [2], btw, has transformed my view of space and space opera litterature. I have a much somber thinking about space, the theory in the books, is that there are species that want to wipe all their opponents and the only way to survive is to hide. Another take at this is from Charles Stross in Singularity Sky [2], where a whole human fleet is again destroyed by aliens like a flick of a switch. I know these two are science fiction, but like comment, a nuke won't save the day when aliens have been forced to live in the void for the travel time and have engines capable of taking them here. 1. https://www.goodreads.com/book/show/23168817-the-dark-forest https://www.goodreads.com/book/show/23168817-the-dark-forest 2. https://www.goodreads.com/series/189931-remembrance-of-earth-s-past https://www.goodreads.com/series/189931-remembrance-of-earth... 3. https://www.goodreads.com/book/show/81992.Singularity_Sky https://www.goodreads.com/book/show/81992.Singularity_Sky

  I think 2001: A Space Odyssey did an excellent job with its treatment of this dynamic. It still blows my mind that it’s 53 years old.
