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 :)
