QE is the financial version of Iraq: you can't stop the occupation, for what you created is a monster.
I don't think this is true. QE was designed to attempt to prop up the economy. Once the economy is able to grow at a strong enough pace on its own then QE will no longer be necessary. Now getting the balance sheet of the fed back down to more normal levels is a much different story.
QE was designed to prop up the banks (see dodgy dealings in regards to Lehmann, AIG, Hank Paulson).
The economy cannot grow at a strong enough pace because it is still choc full of toxic debt and derivatives. If QE stops, everything tanks and the deflation that has been trying to take over and purge the system of its excesses, does its job. Don't wait up or hold your breath for green shoots, they are not coming - it's been 6 damn years. Soon we'll be calling it the lost decade.
Regarding QE / Iraq, both 'occupations' were dishonest.
Victory was declared on numerous occasions only to be shown as false.
Both are at a certain point where withdrawal sees the situation deteriorate quickly, ensuring that you can never really leave.
