South African Unrest clarification
The text on this card was changed from the second edition to the Deluxe Edition, altering any country to any countries.

From the Official FAQs:


  #53 South African Unrest
  
  Note the Deluxe Edition card text allows the option of 2 Influence in "...any countries 
  adjacent to South Africa." effectively allowing one each in Angola and Botswana.


This allows the 2 influence to be placed either in Angola or Botswana or split between both countries, getting one each.
