"Now, with two U.S. aircraft carrier battle groups in the region, is there a growing chance the United States could find itself at war with Iran? Joining us now, retired U.S. Army Colonel Pat Lang, former chief of Middle East intelligence at the Pentagon.
Pat, thanks for coming in.
COL. PATRICK LANG, U.S. ARMY (RET.): My pleasure.
BLITZER: Take us behind the scenes right now, all of the saber rattling. The leaks we're also seeing -- the Seymour Hersh article in "The New Yorker" magazine.
What's going on, in your assessment, behind the scenes?
LANG: Well, a lot of this, of course, is intended to reach the ears of the Iranians. You know, it's -- it's quite a good idea, in a lot of ways, to make sure the Iranians know the United States is very serious about the concerns about them and if they aren't careful, they could end up in big trouble with us.
At the same time, I think that you have to understand that there is intensive planning for how you would execute an operation against the Iranians going on in the military, in response to direction by the president.
These are contingency plans and when they say -- when the White House says that we do not plan to attack Iran, what they really mean is that they haven't made a decision.
