As best ubderstood, diplopolitical protocols often require a lo five of sorts in the tradition of the traditional handshake.
Of course, the obverse is also true - dissing an out stretched hand denotes the innate uncoolness of the proffered shake and disaproval of th regime rep'ed.
Like 44's handshake with the cruel despot of unfree Cuba.
The brief handshake was delivered with the world watching as 44 greeted leaders assembled to make remarks at the memorial service here for Nelson Mandela. But the image — captured by photographers and television cameras — instantly raised questions about its deeper meaning.
Was 44 trying to signal a new effort by the American government to reach an accommodation with Cuba 50 years after the Communist revolution that put Fidel Castro, Raúl’s brother, in power? Or was 44 simply trying to avoid delivering a diplomatic snub at a memorial dedicated to forgiveness?
As Natan Sharansky preached in the essential "Case For Democracy" - despotries use photo ops and shout outs from Free World cats to LOL and crush dissidents and dissident spirits.
"Sometimes a handshake is just a handshake, but when the leader of the free world shakes the bloody hand of a ruthless dictator like Raul Castro, it becomes a propaganda coup for the tyrant"
See, the hand 44 just lo fived is also the very same hand that has signed long time prison terms and death warrants for freedom fighters and cats struggling to be like Great Satan
Ironic and UnCool
