Bibi didn't go to the funeral to avoid politics. high profile figures likeDesmond Tutu have no love for Israel the very last thing Bibi or the South African government wanted was stories in the pro arab SA media or websites discussing the morality of Bibis attendance. Not every head of state in the world attended so Bibi did the simplest thing and was one of the many heads of state who were not there ( Bibi was not the only no show ). Wouldn't even surprise me if Bibi had held secret talks with the SA government about what did they recommend. Only the Israeli leftist media has criticised the decision not to go.
