A hop, skip, quack, jump, and fairly obvious high-energy distillation process away. The national security angle probably isn't a concern here for the same reason that this process doesn't produce good fuel.

Ammonium nitrate is made from ammonia and nitric acid (which is also made from ammonia). Therefore, ammonia is the only necessary direct precursor to ammonium nitrate, which is probably the most relevant oxidizer in improvised explosives today.

Not saying that it should be regulated on the basis of national security, but it’s not like there isn’t a potential security concern.
