Even a faked war of the worlds scare might help, he suggested.
The Huffington Post reached out to some experts who share an intense interest in the idea that earthlings are not the only intelligent game in town -- or space.
We asked, If there were an ET threat and if the U.S. government were to suddenly rechannel its budgets into preparing an anti-alien defense, would that ultimately save our economy? Their responses varied, ranging from skepticism to enthusiasm.
Here is a sampling of their replies emailed to HuffPost:
"I assume the alien attack is a euphemism designed to gain public support for that spending effort. Therefore, my position would be that the alien invasion he proposes to prepare for is with the mythical aliens. They are Hollywood contrivances and conveniently always have fatal vulnerabilities that humans can exploit. The good news in that scenario is we both defeat the evil aliens, and in this case, restore our economy." -- John Alexander, a retired Army colonel and developer of the concept of nonlethal defense at Los Alamos National Laboratory
"Any aliens that have the capability to come here and ruin our whole day by vaporizing Earth or terrorizing its hominid inhabitants, would be centuries -- perhaps millennia -- beyond our technical level. To spend effort preparing for such a lugubrious possibility would be like the Neanderthals organizing their society to defend themselves against the U.S. Air Force. That won't do them much good on the battlefield. But who's to say? Maybe it would improve the Neanderthal economy." -- Seth Shostak, a senior astronomer at the SETI Institute and chair of the International Academy of Astronautics' SETI Permanent Committee
