Bring on the Space Alien Stimulus, says Nobel Stimulunatic [updated]

As the world's economies slip into the Greater Recession from which they had “emerged” only by massaging their numbers, the man who called for a housing bubble to "fix" the American economy during its last Recession  in 2001 demonstrates that mainstream economics has learned nothing since--has not learned that it is not credit creation and mindless consumption that drives economic activity, but genuine savings and real production!

Speaking not on The Onion but on CNN,' Krugman calls for space aliens to attack earth requiring massive defence build-up to stimulate economy. Yes, really:

"If we discovered that, you know, space aliens were planning to attack and we needed a massive build-up to counter the space alien threat and really inflation and budget deficits took secondary place to that, this slump would be over in 18 months. And then if we discovered, oops, we made a mistake, there aren't any aliens, we'd be better –"

Is this the dead end for mainstream economic “fixes” for the crisis their failed theories have caused, exacerbated and extended?

UPDATE: Any Keynesians reading this will snicker quietly to themselves and say things like “But didn’t World War II rescue America from the Great Depression? No, schmucks, it didn’t.

As Dr. Robert Higgs has more than ably shown, the Great Depression continued, and deepened, throughout the New Deal and throughout World War II. The World War II years were a time of shared privation, with virtually every item that we take for granted today either rationed: e.g., meat, gasoline, sugar, clothing; or not available at any cost: e.g., new cars, appliances, etc. The American standard of living throughout World War II remained at an excruciatingly low level that no 21st century American would accept. Meanwhile, unemployment disappeared simply because 16 million able-bodied people were sent to war, paid below-market rates and subject to danger, death, and maiming they may not have preferred to unemployment.
  As [Mary Theroux] earlier detailed in “One More Time: World War II Did Not Bring Us Out of the Depression,” the Great Depression ended in 1946, when 10 million individuals were returned to the ranks of the unemployed, and federal spending plunged 40% in the aftermath of FDR’s death and the abandonment of the New Deal.
If Dr. Krugman would quit reading Keynesian theory and start reading history, he could earn his Nobel and look for salvation not from aliens but from the creative engine fueled by free individuals unencumbered by regime uncertainty and widespread diversion of productive resources to government programs.
