Iran has made overtures to the US on Iraq, Lebanon, and Gaza?

This is one of those second hand stories that could well be about shaping perceptions, but file it away as maybe something.

...previously undisclosed details are emerging of a secret meeting between Iraqi President Jalal Talabani, other senior Iraqi officials, and the commander of Iran's Qods Force, Brig. Gen. Qassem Soleimani, in April, after clashes with Sadr's Mahdi Army in Basra.

In that meeting, General Soleimani "was deeply concerned" and "promised to stop arming groups in Iraq and to ensure that groups halt activities against US forces," according to a description given by a US official to the Monitor.

Soleimani gave Mr. Talabani a "message" for US Gen. David Petraeus, too. He noted that his portfolio includes Iraq, Gaza, and Lebanon and that he was willing to "send a small team" to "discuss any issue" with the Americans.

From the sound of this, the US command in Iraq is highly skeptical.

Later: What does it say that this meeting supposedly took place in April, the US made loud noises about Iran, and then Hezbullah flares up in Lebanon?

Does that mean the Iranians were blowing smoke then? Or that they met the US tone and rejection with an example? Or is this whole thing something else?

And, who leaked this now and for what purpose?

I have a feeling there's alot going on here that we're not seeing.
