Responsible Drawdown?

The phrase "responsible drawdown" in reference to our armed forces in Iraq gave me pause.  What's a "responsible drawdown"?  Why does this phrase bother me?  Is there such a thing as an "irresponsible" drawdown?

And what happened to responsible deployment in the first place?

Remember...there are still 50,000 U.S. troops in Iraq regardless of the so-called "responsible drawdown," and troops continue being deployed every day.  The Administration may paint these as "non-combat troops," but the name doesn't change who they are or what they were trained to do.  (A rose by any other name....)
