And almost immediately thereafter the Prime Minister of Croatia said "That's not in the hands of the President, Parliament decides that, and we ain't gonna veto". And presumably he has a majority in Parliament, or he wouldn't have that job. (Sorry, no source -- TV news the same or next day, IIRC.)

I mean, from TFA:

> Croatian President Zoran Milanović on Tuesday said he would block the admission of Sweden and Finland at the NATO summit in Madrid if he is the one representing Croatia

If he is representing Croatia, and the country's decisions are made by Parliament (the President "has a say" in foreign policy), then isn't his job there only to re-present what Parliament has decided?
