Well, check out the Badinter Commission's findings: That Croatia should not be recognised because it failed two of the criteria for recognition: (1) It failed to provide assurances for fair treatment of minorities in its constitution and (2) it was not in control of its claimed territory.
It must be stressed that Germany recognised Croatia despite the Badinter Commission's recommendation, not because of it. Hence, the Croat pop song "Danke Deutschland".
Anyone who knows the situation knows that (2) would not have been the case had it not been for (1) -- well, aside from some nuts in the Knin area who could easily have been cleaned up and cleaned out.
Correction: "Anyone who knows the situation knows that (2) would not have been the case had it not been for (1) AND Tudjman's heavy-handed tactics -- well..."
