Nuclear deflection seems like a pretty good idea for objects of this size. Even if you don't break it up, you can still detonate it standoff and change the velocity quite a bit, which is good enough.  Also, nuclear deflection is about the only thing we have right now that we can use with a lead time less than several years.

I never got the concern that nuking asteroids would just create a bunch of tiny asteroids. Wouldn't tiny asteroids mostly disintegrate when they enter the atmosphere? 


Yes. Some people on other websites (ah dot com) who are bad at math think that all those asteroids entering Earth's atmosphere. However, I did a bit of quick math. Earth's atmosphere has a mass of about 5*10^18 kg, and the Chicxulub impactor deposited about 10^21 J of force energy. Using the specific heat value for 300 Kelvin air, you get a net heating of about 1/4 degree (assuming the entire energy of the impactor gets transferred to the atmosphere as heat.

      Something I haven't seen discussed on this site before; Soviet/Russian efforts to domesticate foxes by breeding for domesticated behavior. Article in Scientific American here; https://blogs.scientificamerican.com/guest-blog/mans-new-best-friend-a-forgotten-russian-experiment-in-fox-domestication/
      Interesting that there were physical changes correlated with the behavioral changes the Russians bred for.

      It seems like a pretty cool idea to drunk me, though I don't have a spare 7,000 dollars laying around (thanks student loans!). Also, I don't think my cat would approve.

      Strategic Air Command (dot com) shows us:

      I once did some contracting work assisting with a rocket test fire in an Atlas silo. IIRC, they are smaller than the later Titan silos.

      This thread is for discussion of ICBM basing options, as outlined in the linked paper (written in 1980).
      While some of them seem absurd (dirigible basing!), others appear to be more realistic.
