Google data shows a sharp rise in searches for “WWIII” and “US draft age limit” amid escalating Middle East tensions. This surge reflects growing concern about potential military obligations should the U.S. reinstate conscription, even though the draft was abolished in 1973.

While today’s military is entirely voluntary, the Selective Service System still tracks around 16.4 million men aged 18–25. In a national emergency, the government could reactivate the draft, with 20-year-olds being called first, followed by older and younger age groups if needed.

Registration is required by law within 30 days of turning 18. Failure to comply can result in fines, jail time, and loss of federal benefits, including student aid and government jobs. Non-citizens, including refugees and undocumented immigrants, are also required to register.

Draft activation would require both congressional and presidential approval. Once triggered, the system has 193 days to transition from registration to active conscription. A lottery would determine the order of call-ups, using birthdates similar to the Vietnam War era system.

Those selected would undergo medical, psychological, and legal evaluations at Military Entrance Processing Stations (MEPS). Exemptions for college students, married individuals, and people with disabilities are possible, and conscientious objectors may be assigned to civilian service.

While many fear a draft, it’s worth noting that past systems granted numerous deferments and exemptions. If activated, the number actually inducted would be far smaller than the initial pool, and many roles would be non-combat-related. For now, registration remains separate from any draft plans.
