Iraq War causes problems at Walter Reed?

In essence that is what Rep. John Tierney is asking in this article.

Tierney, D-Mass., chairman of the panel, questioned whether problems at the
facility are "just another horrific consequence" of inadequate planning that
went into war in Iraq; a problem created by contracting out work there to
private business, or some other cause.

I think I would rather put my "glass is half full" spin on this situation. You can pretty much guess that this problem didn't just happen over night. In fact, if it weren't for the war the problems in the system may have never been addressed because no one has taken a serious look until now, which we are going into year number four.
