1990 and HSS), assembled together in Croatian National Assembly, have so far failed to deliver anything more than a mere concept. Dragan Čović, president of one of the main Croatian party in Bosnia, Croatian Democratic Union of Bosnia and Herzegovina, said that "all Croatian parties will propose that Bosnia and Herzegovina be divided into three ethnic entities, with Sarajevo as a separate district. Croatian politicians must be the initiators of a new constitution which would guarantee Croats the same rights as to other constituent peoples. Every federal unit would have its legislative, executive and judiciary organs". He claimed the two-entity system is untenable and that Croats have been subject to assimilation and deprived of basic rights in the federation with the Bosniaks. In July 2014, the International Crisis Group published a report Bosnia's Future, among others, proposing establishing Croat entity and reorganizing the country in three entities: Political scientist from Macalester College and Georgetown University, Valentino Grbavac, proposed the establishment of a Croat entity in his 2016 book "Unequal democracy" as the optimal solution. He proposed assigning same powers that Republika Srpska currently holds to new Croat and Bosniak entities, possibly changing borders of municipalities to better reflect ethnic composition and turning Jajce into a Croat-Bosniak district, like Brčko today. Croat entity would also "look out for the well-being and protection of Croats in other entities," while introducing "strong legal protection" and "guarantees of rights of other nationalities" in Croat-majority entity. In his December 2016 essay in the Foreign Affairs, Timothy Less argued that the U.S. foreign policy should accept "the Croats' demand for a third entity in Bosnia. In the medium term, the United States should allow [the entity] to form close political and economic links with [Croatia], such as allowing dual citizenship and establishing shared institutions" as this would enable the population to "satisfy their most basic political interests." David B. Kanin, an adjunct professor of international relations at Johns Hopkins University and a former senior intelligence analyst for the CIA, pointed out in February 2017 that Bosniak politicians' unilateral policy "justifies the Croats' demand for their own entity." Constitutional principles Constitutional Court of Bosnia and Herzegovina in its landmark Decision on the constituency of peoples ruled that: Territory It is unclear what territory Croat federal unit would encompass. It is generally assumed it would comprise Croat-majority municipalities in the country, but the criteria haven't been clearly defined
