Hearing they want to make the Vladdy-Voloddy meeting first, then Trump would join after.
The name of Budapest comes up over and over for one of the meetings at least. Fidesz media says it might not work out, blaming Kiev, saying Ukraine wages a hybrid war against Hungary. Beyond that how viable would it be? I dunno why not, surely Putin would not be arrested so for him it's safe. Any arguments pro or contra are all weak, just "meh sure". For me the place as a choice feels insignificant, like Orbán was blown up by the media as the great ally of Putin and Trump, but him is insignificant as well, he is just used for media noise.
Switzerland also loses significance, and it feels it became the gathering place of "leftliberal globalist" elite, center of Zelensky begging tours.
China could suit for a trilateral meeting maybe even for a P-Z too. They seem closer to Russia, but they sell crap to both sides that used by their militaries (as weapons too).
