you know I wonder if my english is superior to americans because I answered your question with a question that showed it was virtually impossible for the blacks to revert to precoloniall borders on their own..
to quote your "What's stopping them?"
well i have already questioned your english here so I doubt it is superior to Americans. danny81 for sure, but Americans? I think not. no doubt you are educated. too bad that education hasn't led you to an understanding.
