The US has been fighting deflation not inflation. The point of QE is to solve the zero-bound interest rate problem where the central bank can't reduce rates below zero. If there ever were to be an inflation threat here (which conservative economists have been inaccurately predicting for 8 years now) there is plenty of room for the Fed to raise rates in response.
