Barack Obama and Raul Castro will both offer eulogies for Mandela at a sweeping memorial service to be held at the Soweto stadium that hosted the 2010 World Cup final.

While I do realize this is suppose to be a funeral and not meant as a diplomatic mission... I hope President Obama has time to press the flesh so to speak with other leaders that he would normally never be anywhere near...
A hand shake is not an earth shattering event... But if the opportunity to shake hands with Raul Castro presents itself I hope he takes advantage of it... Breaking bread would be even better...
I know many other dignitaries will be there, hopefully he can cross paths with some of them too and shake many hands...
The world needs Peace above all else and this is a historic opportunity... If the president were to stay just one extra day to do some meet and greet I believe it would pay excellent dividends...
Just one old redneck opinion...
