Since the United States and NATO helped overthrow Ghaddafi in 2011, millions of migrants from Africa and the Middle East have poured into Europe. Many transited from Libya.

This is all well known, and all signs point to this trend accelerating. What's your take on where this is going?

Doug Casey: First, it's a pity Ghaddafi was taken out. Another disastrous US policy decision. Not that he was a nice guy—no one running an artificially constructed nation-state can be. But it was at least a stable situation. Now it's been replaced by a bloody and costly war. And it's complete chaos. Nice work Hillary and Obama. But let's talk about Africa at large.

Africa, or at least migration in and out of Africa, is going to be the epicenter of what's happening in the world for the rest of this century.
