I believe they call defense a Nuclear Weapon, personally. A Really..Really..BIG one. If we bury the idea, for a moment, that warheads can't have
constructive use, then that is a very effective solution in my opinion. Some propulsion to get it a good distance away from Earth would be
awfully thoughtful of them, of course.
NASA Near Earth Object Catalog
The quick display there only has 2 of the entire bunch over 1.5 kilometers in diameter. The fireball (total obliteration) of Tsar Bomba is estimated
to have been between 1.3 to several Kilometers
across. The blast wave apparently reflected back with enough force to tweak that measurement out
of whack, although the cloud at base was 25 miles across
Several space based detonations have already been done, back in the 50's. A few threads around ATS cover them. So they ought to have a fair idea of
how big 'big' actually is in that environment.
Instead of using tech we already have, stigma and taboos or not, I'm sure they'll figure out entirely new things that'll take forever to develop,
longer to make and cost the treasuries of small nations to pay for.
