While the movie goes into great details about the dangers of nuclear weapons, it neglects to mention an important possible beneficial aspect of them.
There are massive objects traveling in the space called NEO (near-Earth object) which come dangerously close to the Earth from time to time. Then there are those called Earth-Crossers whose orbits actually intersect that of the Earth. Astronomers tell us that a collision with such an object is inevitable some time in the future and it could be catastrophic for all life on our planet.
If such an object is ever spotted coming at us (Jupiter had such an event only a few years ago) then those much-maligned nukes and ICBMs may be the only weapons in our arsenal with which to defend ourselves and we will not have a whole lot of time to manufacture them from scratch if we do not have some already on hand. While it may not be possible (or even desirable) to destroy such an object altogether, its trajectory may be deflected just enough to make it miss the Earth.
Therefore it might be wise for us to think things through before taking any drastic measures for their total elimination.
