As for Croatia, to the surprise of no one, we have failed to make the final yet again. The last time we made it was 2016, which was incidentally the last time Bosnia and Herzegovina competed as well. And before 2016, we have to go back to 2009.
But is not coming back... ever. Ex-yu was a big thorn in the ESC's eye for years, but alas they managed to solve it for good.
