How few Bosnian Catholics will there be in another five years?

CNA notes an interview with the Franciscan provincial superior in Bosnia:

The provincial superior of the Franciscans in Bosnia, Father Mijo Dzolan, said last week that because talks over reform of the post-war constitution of Bosnia-Herzegovina have collapsed, many Catholics have been forced to flee the country to escape discrimination.

 
... Father Dzolan explained, “Nothing has changed for the better for the Church. Catholics are still discriminated against by the constitution of Dayton (the Balkan peace agreement reached in 1995).”

 
... “At a political level there is still division--some are pressing for the first steps of change, while others simply don’t see it as essential,” he said. Until the constitution is changed, the priest said it is difficult to see an end to the crisis which has driven more than half of Bosnia-Herzegovina’s Catholics out of the country since the start of the Balkan war.

 
Catholic Bosnians have migrated in large number to Croatia, Australia and the United States.  Who is discriminating against these people, and why?   It is fascinating, in a quickly forgettable sort of way, that that issue isn't addressed at all in the CNA piece.  If one doesn't name the adversary, perhaps he will go away: it reminds me of my childhood.
