"Wasting" of Military Lives

Michelle Malkin criticizes Obama for saying this:

OBAMA: We ended up launching a war that should have never been authorized and should have never been waged and to which we have now spent $400 billion and has seen over 3,000 lives of the bravest young Americans wasted.

She says that Obama argued that "each and every member of the military who volunteered to serve and died in Iraq wasted his/her life."

I think she's mis-characterizing his statement, though. He's not arguing that they wasted their lives by joining the military. He's arguing that Bush wasted their lives by sending them to Iraq.
