The chaos and violence in Somalia continues to intensify. Dozens died in the shelling of a public market in Mogadishu on Monday and more than 100 in total have been killed in scattered fighting in the capital in what observers are proclaiming to be the worst fighting in Somalia in months as Islamist insurgents seek to impose their will on whatever remains of the country, which has operated effectively without a government for years. Thousands more have fled the region and hospitals are filled well beyond capacity. Of all of the intractable situations on earth, Somalia's might be the most insurmountable. It is hard to begin even to conceptualize a solution to that country's ruptures.
