One was in the mid 1980's when Moammar Khadafi (who during that period was close to Louis Farrakhan) called upon American Blacks to "rise up against" their American White Suppressors and revolt.
Another was in the early 1990's when Saddam Hussein did the very same thing - he target the American Black Man to rise up against the White American suppressors and revolt.
Blacks are specially targeted by Islam as very prime for proselytizing and converting to Islam. This happens very often in American prisons, where angry Blacks and Hispanics are being converted to Islam in large numbers with the converts being released upon society to practice their new "faith" (consider Joseph Padilla).
This phenomenon bears watching closely. Al Qaeda is watching it. Islamic leaders abroad are very interested in it.
Wow. Scary. I never knew/thought of all that. Thanks.
