Are you implying that all those middle-eastern countries were failed states, ruled by hordes of warlords? For instance, I vaguely remember Iraq being a pretty fine country; for decades, a lot of engineers from my country went there, and we had a pretty good economic cooperation. Then the US came and bombed the living shit out of it.
As for Africa, isn't most of the mess the result of Europe coming there, destroying their local governance, abusing them for a while and then withdrawing, leaving a huge power vacuum behind?
