It Was Another Misunderstanding Or Another Joke?

On his back to the US, on Air Force One, Trump was asked by a reporter whether he meant the US will be doing underground nuclear detonations, to which Trump replied with "Yes. You will find out [details] soon, but yes, we will be doing testing".

Chris Wright, our Sec. of Energy, is now trying to walk this back, on Fox News, by saying that "this will not be a nuclear test at this time".

So, if it's not a nuke test, they will have people jump up and down to simulate one?

I notice the White House is doing its best to make sure the topic is never brought up. Wonder why.
