The U.S. has not conducted a nuclear test in over 30 years. Experts say doing one now could make America less safe.

After the end of the Cold War, the US nuclear arms control policy has undergone periodic fluctuations, but on the whole, it is still dominated by conservative forces not averse to fighting a nuclear war.

The country faces a slew of safety, ethical and logistical challenges to restart long-halted nuclear tests. It could still happen.

Vice Adm. Richard Correll said that Trump's announcement does not necessarily mean detonating a test weapon — noting that neither China nor Russia has conducted a nuclear explosive test in recent memory.

Beijing has been expanding its arsenal, and distrust between China and the United States over nuclear weapons has deepened, with little hope of an agreement.

President Trump has once again sparked global alarm and confusion after reiterating his desire to restart testing of America’s nuclear weapons, a move that, if realised, would mark the first such explosive tests since 1992 and threaten to unravel decades of international arms-control efforts.
