On the Assertion by Paul Krugman and Chris Hayes that FED Chairman, Ben Bernanke, Hasn't Been Doing ENOUGH

It's insane. Mr. Bernanke has essentially tripled the monetary base over the past four years, issuing more paper-money than all of the previous FED chairmen COMBINED!!! And he's also kept the interest rates at zero or pretty damn close to it. What, pray tell, WOULD be enough for these two discredited individuals (Krugman thinks that the world should be building up its military in preparation for an alien invasion and that that massive misallocation of resources would in fact get the world out of its recession - he's never once read Frederic Bastiat's "Broken Window Fallacy" OBVIOUSLY) ? I mean, do they completely want to destroy the value of the dollar here?
