Asteroids security

Should nuclear devices be used to stop asteroids?

Nuclear devices aren’t required to build infrastructure or extract resources. These activities can readily be done with non-nuclear technologies, hence we do not hear the construction and extraction sectors pushing for access to nuclear devices. But there is one sector in which nuclear explosions appear to be the best option available: protection from asteroids and comets, collectively known as near-Earth objects, or NEOs. The impact of an NEO hitting Earth could be catastrophic to humanity.
