Yes, I think everyone is a bit wary of Wilders, but it's also hard to deny PVV is the largest party – you can't "just" ignore then either. VVD is probably at least willing to be convinced it can work.

On immigration VVD is closer to the PVV that they'd like to admit, but PVV is also pretty left-wing on a lot of other issues – that's probably going to be a harder problem. The reason Rutte 1 failed was the budget, not immigration.
