United States: Men Aged 18-25 Automatically Registered for Military Draft Starting December 2026

Starting December 18, 2026, the Selective Service System will automatically register American men aged 18 to 25, ending the requirement for individual self-registration. This measure, included in the National Defense Authorization Act signed by Donald Trump, shifts the registration responsibility to the federal government. Registration does not constitute a military commitment but feeds into a potential mobilization register. The White House spokesperson clarified that a return to conscription is not planned.
