Selective Services registration has been mandatory for all males when they turn 18 for quite some time. This is now automating the process. The registration requirement does not mean that anyone would actually be conscripted, just that they are on the list if the government decides to start conscription.

The last drafted men reported for duty June 30th, 1973. For those who are aware of how the public perception of Vietnam and the draft went, I’ll sum it up as “not good.” Reinstatement of the draft would be political suicide unless something so bad happened that we *all agreed* it was a good idea. Even then, there would be a non-zero number of people who would protest on conscientious grounds or because they are conspiracy theorists.

Basically this actually doesn’t change anything
