> which i'm sure the current administration would honour

It would've been the same administration as the one doing the negotiations, so I would assume yes.

In general I think there's a pretty good understanding between the legislative branch and the executive branch. The Netherlands has always had coalitions. Also, every single government will talk to the other parties.

I'm not sure what country you're referring to but the Netherlands has a properly functioning democracy. The only problem it has is splintering into too many small factions making coalitions super hard

> executive branch

I didn't think the Netherlands had one of those.

'het kabinet' or 'de regering' is the executive branch in NL. You don't need a president to have an executive branch.

Eerste/tweede kamer. Legislative, make the laws Ministers/staatssecretarissen, executive, implement policy Hoge Raad etc, legislative.

Look up trias politica

There are certainly countries that have it worse, but Netherland has some weird political games being played sometimes.

The voters don't always deal the cards favorably for the coalition system. Compared to a 2 or 3 party system, I think I still prefer the coalitions though as it forces them to negotiate
