Sand and I agree on a lot of things. And we agree on a lot of what he has written today.
I would add that Africa has as much variation as North America. There's a lot of difference between Egypt, Morrocco, Tanzania, South Africa, and Ivory Coast. As much as between Canada, the US, and Mexico. There have been instances of local terrorism across Africa, Asia and all regions where low-income countries are prevalent.
However, I don't think there is as much chance of terrorism in South Africa as there is in the West. South Africa is a truly non-aligned state that abhors terrorism. Don't forget, this is the only country to have nuclear weapons and to destroy these.
As for European settlers, they did good and bad in Africa. Those who did bad raped the land, plundered its wealth and people (in slavery), and deprived a people of their cultural identity.
The regional wars of the 1970s still characterize Africa for many people. But what many don't understand is that those wars resulted in part from the indiscriminant border setting by European colonists, who simply carved out territories without reference to existing boundaries. Let people from Canada take over much of Ohio and see if Ohioans would not fight to regain their land.
Africa is undergoing great change. Tribalism and ethnicism are much less important aspects of African identity today. There is a good website
www.afrobarometer.org that has lots of research on this and on topics of government, democracy and the like (co-hosted by Michigan State). Some problems remain in central Africa and with business ethics in many countries, but in the main Africa has begun to move toward good governance, rule of law, and economic maturity.
I have lived through a revolution and I lost good friends to combatants from both sides of the South African war to unseat Apartheid. I know sub-Saharan Africans well. In my experience, they are people with great human dignity who prefer cooperation to conflict. We can learn a lot from them, and they from us.
Ubuntu (http://www.ubuntu.org/) is a core African cultural value that refers to the fact that a person is a person only through other people. African culture recognizes a person as an individual and as a member of a group. Although Nelson Mandela gets the credit for the peaceful transition in South Africa and he is a very wise and exemplary person, he would be the first to tell you that he was only acting on ubuntu principles.
So, although I think there are regions in Africa where international terrorism could well be fomented, I don't think the South African government is likely to be harbor terrorists or its people approve of their actions.
