At the 31-second mark N.Y. Times columnist Paul Krugman suggests that if there was a huge government-spending program brought about by an emergency, like the spending prompted by the Great Depression and World War II, it would bolster our economy and make it robust, even, in less than two years. And then at 1:04 he theorizes that such a program could be brought about by the threat of invading space aliens.

Almost exactly the same point was made in a slightly different context by President Ronald Reagan in December 1985.

Speaking about sharp nuclear-policy differences between himself and Russian president Mikhael Gorbachev, Reagan said, “I couldn’t help but…when you stop to think that we’re all God’s children, wherever we live in the world, I couldn’t help but say to [Gorbachev] just how easy his task and mine might be if suddenly there was a threat to this world from some other species from another planet outside in the universe. We’d forget all the little local differences that we have between our countries and we would find out once and for all that we really are all human beings here on this Earth together.”
