Their sentiment is that Trump intervenes by whining to Mark Rutte, who seems to be the only European Trump is actually willing to listen to, at the expense of course of giving up all his dignity in calling Trump, literally, Daddy [1].
And I would not put it past Trump to do that... I mean, that's what he already did regarding Tiktok.
With Trump nothing is impossible any more, especially if he or someone in his circle stands to make or lose money. And that's the greatest danger in the US turning into a full blown banana republic.

It seems to me that there is no way that Trump could overturn this decision via Rutte that Trump couldn't accomplish on his own by just threatening the Netherlands directly.
