Cuban president Raul Castro shades US president Barack Obama

  

After an event in Havana Cuba, US President who is the first American president to visit Cuba in 88 years tried to hug Cuban President Raul Castro, but Castro refused to hug him, instead, he blocked the hug and raised his Obama's hand like a champion and smiled. During that awkward moment, President Obama smiled, waved and walked ahead of the Cuban president as they both walked away from the podium. A lot of people think it was disrespectful. What do you think?
