Yes he said that as a joke, not a good joke I admit...I guess you also believed President Reagan had ordered Russia outlawed and bombed?
He only said it was a joke when he realized it was not well received. Another problem. You believe that? Have the courage of your convictions. Do not try to weasel out of it. Stand up for what you believe. And the Reagan analogy does not work ..sorry.
Now he says it was not a joke. He said it may be a fence..it may be electric. He said he “is not walking away from that idea.”...so..a joke? no...it was not.
