Google data shows a surge in searches for “World War III” and “U.S. draft age limit” following recent Middle East tensions. The spike reflects growing public concern about whether conscription could return if a global conflict erupts. While the United States has not had a draft since it was abolished in 1973 after Vietnam, the Selective Service System remains in place, maintaining detailed procedures for reactivation in a national emergency.

Currently, about 16.4 million men between 18 and 25 are registered, compared to 1.3 million active-duty members. Men aged 20 would be called first, with younger and older groups following as needed. Refugees, permanent residents, and even undocumented immigrants are required to register. Women are not currently included, though officials note the system could expand if laws change.

Failure to register carries serious penalties, including fines, prison, and loss of federal aid. Should Congress and the President authorize a draft, a lottery system would determine call-ups, similar to Vietnam-era drawings. Though America’s military is fully voluntary today, these discussions highlight lingering anxieties over how a major war could reshape service obligations.
