Is this Irans version of Keynesian Economics???

Iran warns 'we have dug mass graves for your soldiers' in response to U.S. attack threat

""Iran has dug mass graves in which to bury U.S. troops in case of any American attack on the country, a commander of the elite Revolutionary Guard said today.He added that a military strike would spark an 'extensive war' in the region...""

This is either a cruel joke, OR it is Irans version of extreme Keynesian Economics---if you have to, pay people to dig holes and fill them back up...Quite the economic stimulus plan...
