I can't remember if other presidents have ordered flags at half staff for any leaders outside of USA? Or people outside of USA? does any body know if it is proper protocol to do this for Mandela?
No. We do not lower flags for non-citizens. It's never been done for Queens, Kings, Popes...if anybody should have been so honored, it would have been Lady Thatcher.
Instead, we have a BLACK president honoring a BLACK non-citizen leader of the Communist-leaning African National Congress.
And he's hauling his bony ass and his wife's to South Africa for the funeral. Hell, he doesn't even go to the funerals of US Senators, yet he's got to pay homage to one of his homies.
