ELI5: If we had 10 years notice of an impending meteoroid strike, could we deploy thousands of nukes in its trajectory and use the shockwaves to stop it?

Yup.

But...

* they'd have to change international non-nuclear-weapons-in-space treaties first

* those nukes would have to be lifted in orbit and placed and kept on the right trajectory. That would be a shuttle-load of money.

* the nukes would pretty much have to detonate in contact with the asteroid (because there's no shock-transmitting air in space), and the object would have to be solid enough for the nukes to "nudge" it so you wouldn't just transform it into a cloud of sand still aimed at us. 

* It couldn't be so big that nukes couldn't effectively move it (say, if Jupiter was inbound).

A better and safer solution, given the time and the interest, might be to build a low-thrust engine on it instead.
