Rising global tensions have brought renewed attention to the possibility of a U.S. military draft. Although conscription ended in 1973 and the country now depends on a volunteer military, the legal system that would allow a draft is still in place. This has led many to wonder how it might function if a major conflict required more troops than volunteers alone could provide.

Recent world events have fueled these discussions. Ongoing war in Ukraine, instability in the Middle East, and increasing rivalry between major powers have heightened concerns about global security. Experts note that modern warfare can escalate quickly, especially with cyber threats, advanced weapons, and new technologies like autonomous systems.

Public opinion reflects this growing uncertainty. Surveys show that many people believe a large-scale conflict could happen within the next decade, with some even concerned about nuclear risks. As a result, the U.S. Selective Service System—largely ignored for years—is back in the spotlight, with questions about how a draft would actually work if needed.

While the U.S. moved away from mandatory service after the Vietnam War, the Selective Service still requires men aged 18 to 25 to register. This doesn’t mean a draft is coming, but it allows the government to act quickly if one were ever approved by Congress and the president during a national emergency. Not registering can lead to penalties, and there have been discussions about updating the system by connecting it more closely with federal records in the future.
