I was about to say I thought the other major right wing party didn't want to join him, but I saw your subsequent posts discussing it. I guess we're just waiting for the negotiations to start now, if they haven't already?
On the climate change and nitrogen emissons I'll have to take your word for it. But I still don't think I see the disaster. Whatever measures he can halt/enact even with a majority won't really matter to anyone but the Dutch people who are invested in this. But I take your point, he could make a national difference there maybe.
I had a quick look at
Dutch immigration statistics (I guess both EU and non-EU are grouped together). Net, it went up from 107 000 to 223 000 from 2021 to 2022. So I'm not sure what a hard stance on immigration would look like? Cutting it in half, for example, sounds drastic, but then when you look at the numbers it really just means going back to how it was the previous year. Going even more drastically about it might bring you back to early 2000s level at around 20 000 per year. Unless he's actually going to pick a fight with the entire system he operates within, I don't think he'll be able to do anything other than reign it it a little bit. My very surface take on Dutch politics
