shaking hands?

Look what the Pope did to the world leaders. And our dearest President Khatami even had a chance to socially engage with President Katzav. Whether they actually shook hands or not has left everyone in doubt. Khatami has been reported to deny the allegation and on the other side Katzav sounded quite excited about it. School kids are we now?
I truly appreciate Bashar Assad's approach. Yes I did it; but it didn't mean anything ... Well put! Only if he could teach his Iranian counterpart ....
