Not much of a dictatorship if the dictator concedes defeat after an election that was possible for him to lose.
His options were limited. Aside from his tirades against the EU, he was completely dependent on it, as it financed half the country – Hungary was the largest per capita recipient of EU funds. This was also the reason why he never seriously attempted to leave the Union.
He could now take certain steps, such as eliminating press freedom, but election fraud on the scale that would have been necessary to skew this election would have led to sanctions.
True, it's not so much a dictatorship, more like just a certain type of mindset. Shared by Trump, Vance (I guess), Elon, and the AfD party, Le Pen (maybe) and more.
What do we call this mindset? Right wing authoritarianism? Anti-immigrant sentiment? Poland next door to Hungary is also very anti-immigrant and proud of it (everyone from Duda onwards).
