Already it sounds scary.

OK, so, Jeff, this gives like a real sense of what it was like to visit those tunnels. And like Tim Beller said, is that the U.S. is following these rules. Right.

OK, so, Jeff, I can see now that we could be at this precipice of a return to nuclear testing because we're at this like very unstable moment right now in the world. Nobody like no country wants to go first. But if one country tests, the other countries are likely to follow. Right.
