Serbia and Kosovo awkwardly embrace Israel

IT IS RARE that events in two of the world’s most enduring troublespots—the Balkans and Israel-Palestine—spill over into each other, least of all in a peaceful way. But on September 4th President Donald Trump telephoned his friend Binyamin Netanyahu, Israel’s prime minister, to say he had persuaded the leaders of Serbia and Kosovo—once part of the same country, now mortal enemies—to give Israel a warm embrace. Kosovo and Israel, he said, would recognise each other. And both Balkan countries, flouting the policy of the European Union, which they hope to join, will recognise Jerusalem as Israel’s capital.
