Energy Secretary Chris Wright revealed the U.S. will not be testing nuclear explosions, putting to rest questions over whether the Trump administration would reverse a decades-old taboo.

President Trump and one of his top cabinet officials are sending mixed messages on how the U.S. government is handling the most destructive weapons in the world.

If Trump’s move provokes the start of testing by China and Pakistan, India will need to rethink its own self-imposed moratorium put in place after the nuclear tests of 1998.
