Secretary of State Hillary Clinton was in Bosnia on Tuesday, reaching out to Muslim, Serb and Croat politicians, as well as university students, to try to persuade them to put aside their past disputes and prepare the country to eventually join the European Union.

But Bosnia desperately needs to reform the constitution that was put in place to end the war -- it achieved that aim, but has since paralyzed the political system.
