My opinion is that Bosnia-Hercegovina has for the last 25-odd years been an artificial state propped up by foreign interests. The artificial administrative segregation of Republika Srpska from the Bosniak-Croat Federation (themselves no true friends to one another) and the fact that the most powerful government position, the High Representative, is essentially a NATO/UN/EU-appointed dictator who has power over all laws and political appointments create serious issues for the country.
The article notes this as it says "Sarajevo is choking in smog, that [the regional governments] embezzled money in the Covid-19 crisis, that the death toll in Sarajevo is worse than during the war, the fact that half of the country is living in poverty, that we have completed exactly zero reforms, that no laws have been discussed in the parliament for months.” Is it any wonder that the Serbs are unhappy with this arrangement?
At the same time, Serb separatism must be viewed with suspicion if attempting to regain control of parts of the Bosniak-Croat Federation is one of their plans.
It is important to remember that the submitted of this report is Christian Schmidt, the arbitrarily-appointed High Representative who may be interested in making sure that his own political power and that of the organizations he represents is not diminished. Remember that the articles says that "perpetual and worsening sense of crisis allows the country’s leaders to disguise their failure to govern" and "collectively politicians hope to win points on this crisis and citizens are the only losers as expected."
Civilian rule was supposed to be returned to Bosnia-Hercegovina under the Dayton Accords, but a quarter century later none of Bosnia's foreign supporters have any interest in doing this, instead running a de facto colony. Whenever there is a potential threat they will double down on the arcane 'government' they have created. It is time for independence for Bosnia-Hercegovina. I am not sure how the best way to achieve this, but a continuation of the current situation only harms people.
