Sure. Instead of focusing on what could have been a MAJOR problem for world leaders at Mandela's memorial service with a guy pretending to be something he wasn't, lots of noise today about Pres Obama shaking the hand of Raul Castro out of courtesy...Frankly, if Obama walked past Castro, who was sitting with other world leaders, as if he didn't even exist I would be the first to say the president lacked social grace and I'd be disappointed.
Also, Cuba has held American citizen Allen Gross, a U.S. subcontractor, in a Cuban jail for 4 years and if the U.S. can act civil to Cuban leaders it may help Allen Gross' situation.
