Jeff Jacoby rightly calls for a halt to requiring any Americans to register to be conscripted . Here’s his conclusion:
The creation of the all-volunteer force  has been one of the most successful policy shifts in US history. Short of some catastrophically existential threat to the homeland, mandatory conscription is never coming back. That being the case, what justification remains for making young people register?
Selective Service has outlived its usefulness. It ought to be consigned to history. Let my son’s cohort be the last one required to sign up for a draft that will not be needed again. Congress shouldn’t just end male-only draft registration. It should end draft registration, period.
