On October 31, 2025, President Donald Trump wrote on his social media site. He said the United States will start testing nuclear weapons again.
He said this is because Russia is testing new weapons. Trump’s post made many people ask questions.
A nuclear test is a controlled explosion of a nuclear bomb. Countries do it to learn if a weapon works.
The United States last did a nuclear test in 1992. Russia stopped in 1990, and China in 1996. Only North Korea has tested in this century.
Most countries have agreed not to test. If the United States tests again, other countries may do the same. This could start a new arms race.
Experts also say a safe test would take years to prepare. The U.S. already learns about bombs without big explosions.
Some experts think new tests would help China more than the United States. They say it makes no sense for America.
They worry that Trump’s mixed messages create danger. One day he talks about removing all nukes. The next day he talks about tests.
