About two years ago I read a piece saying that Yemen was only a few years away from running out of water. Separately I read that the country had the world's second largest concentration of firearms per capita.
This is a very, very bad combination. So yes, we all should have seen this coming. With the country now beset by southern secessionists, northern rebels in the mountains, and possible al Qaida infiltration, Yemen is the next Middle Eastern basket case.
