This is fantastic news for Ukraine. Had Simion won it would have left Poland as the only country with a pro-Ukrainian government bordering Ukraine.
Yes, indeed it is good news. Also, Nicuşor Dan is likely to be more active on the foreign policy scene than the former president (Klaus Iohannis), who was very useless and indiferent to anything happening in the world.
Nicuşor Dan may actually be the head of state with the highest IQ among country leaders, as he was a two times gold medalist at the mathematics olympics when he was young, and he is still in his prime (55 years old). He managed to navigate very skillfully the trashy Romanian political landscape, and despite not having a political party, he ended up being the mayor of Bucharest and now the President of the country. He is a strategist who thinks many moves in advance, and he will probably use his skills to improve Romania’s standing in the EU.
Since Russia clearly favored Simion and Georgescu and was 100% against Dan, I expect him to be very hardline in his pro-Ukrainian stance. He will probably forge very strong bonds between Romania and France, as he is fluent in French and has studied for two years in Paris at the Sorbonne University, and was actively supported during his campaign by Macron. I expect Romanian-French ties to strengthen a lot during his term.
As for the Polish elections, in the first round the pro-Ukraine candidate got 30% of the vote and the pro-Russia candidate got 29% (after exit polls), so we shall see how things go in two weeks time. Maybe Simion’s loss in Romania will be followed by a loss in Poland of his pro-Russian friend.
