I was in Kenya at the time of the Mau Mau, Aka, and it wasn't pretty, especially for the thousands of innocent Africans butchered and terrorised by the Mau Mau thugs masquerading as freedom fighters. Jomo Kenyatta, the first President of independent Kenya, who was a very tough cookie indeed, bore no grudges and was very harsh with his own people when he thought it necessary. It's not nice and not right but it happens that way, especially in Africa.
I can't remember who said something like...Patriotism is the last refuge of the scoundrel..was it Cecil Rhodes, perhaps? There is an element of truth there somewhere, I'm sure, but not the certainty of being proud of the nation's resistance during say, the Battle of Britain.
