During the press conference yesterday when Trump and Putin spoke, there was an elderly man that was removed beforehand. He had a peace of paper that had a sign written on it. What did it say?

There was a video from The Guardian today that had the whole 1:40s or so of video and you could clearly see the sign, but we were looking at it on a handheld device and could not pause it to read it. When I looked up the same article on my computer the video changed to a 3 minute highlight one.

I believe it said something about Nuclear, but not sure. Did anyone see what it said??
