About 4 minutes before the end, the narrator says something like this:
"Nuclear Fusion has never been achieved on Planet Earth."

Should have said, "CONTROLLED, SUSTAINED nuclear fusion has never been achieved on earth". Hasn't the Producer of this show heard of the "Hydrogen Bomb"? Or, if she has, what does she goes on inside one of those horrible things? (No, your city isn't being blasted into oblivion by a few unfriendly hamsters, with large claws, hidden inside the "warhead".)

BTW, the first experiment in which Nuclear Fusion was recognized to have taken place was done in 1932, several years before anyone thought of it's possible use in WMD's. Experiment Team led by Mark Oliphant, at Cambridge. And also BTW, the Pulitzer-prize-winning cartoonist (Pat Oliphant) happens to be his nephew.)
