The Nazi Croatia expression is well worn. Unlike Bosnian Serbs, Bosnian Croats do not have their own political entity. Bosnian Muslims do not allow them to elect their political representatives. The current Croat representative was elected almost solely by Bosnian Muslims having received less than 1% of the Croat vote. Of course Croats do not accept such political games.
There is a belief in Croatian intellectual circles that Erdogan will blackmail NATO to support Bosnian Muslims. Whether the right way to help Croats is our blackmail of NATO is questionable, but the Croatian president alone holds this position. The prime minister and the foreign minister support Finland's and Sweden's admission.
If Bosnia and Herzegovina tries to enter NATO and the EU, we should block it until Bosnian Croats receive political equality.
