Another big artillery day!
The country where a pro-Russian party won the elections was Slovakia, not Slovenia. It hasn't been "one of the biggest supporters of Ukraine" and is a fairly small country.
That said, there's certainly some reason to worry about the trends with support for Ukraine. US politics has been worrying at least since 2016 . Also,seems like the threat is very real that with Biden's term we might only have gotten a breather.
