It might be a great idea, but neither the spineless U.S. Congress or Bush will do a d*mn thing seeing as they love Mbeki, Mandela, and the rest of the communist ANC crowd. I think South Africa will mirror Zimbabwe in a year or two. Gold and diamond miners better beware too...the ANC is gradually moving towards confiscation of those industries as well. Get your gold now while it's cheap, by the time SA has it's way, production of those commodities will certainly be adversely affected when those industries are nationalized or turned over to "black" groups.
I think this to be sage advice.
