Bosnia on the brink: Bosnia is facing its worst political crisis since the end of the bloody Yugoslav civil war in 1995, which pitted ethnic Bosnians against Serbs and Croats and left more than 100,000 dead. What's going on? Well, when that war ended, the peace agreement created a special enclave within Bosnia for ethnic Serbs — the better to keep warring ethnicities apart. This has always been a messy arrangement, but now the nationalistic leader of that enclave, Milorad Dodik, is threatening to secede altogether, amid a spat over new laws meant to ban denial of the genocide that Serbs carried out against Bosnian Muslims during the war. A breakup of Bosnia could quickly lead to serious violence, and both the EU and US staunchly opposed the move. But Dodik is undaunted. He says that Serb-only institutions will be in place as soon as November. Asked how he'd pull this off, Dodik — who recently oversaw provocative military drills that spooked Bosnia's other ethnic groups — said "as the Slovenes did it." That's a not-so-veiled reference to the breakup of former Yugoslavia, which led to years of bloodshed. Indeed, it's not a good omen, and is raising fears of a return to the deadly violence of the 1990s.
