Only symbolic measures are being taken: barring two especially extremist ministers entry and air drops which are pointless and even dangerous.

The former is pretty useless. The latter is just playing by Israel’s rules. Israel ‘allows’ European planes to drop aid over Gaza. Why does Israel allow this? Because it gives ‘friendly’ countries something to show to their increasingly anti-Israel populations - it’s meant to release some of the pressure with ‘good news’. By participating in these droppings, the Dutch government is allowing Israel to go on starving the Gazan population. These droppings are criminal.

Veldkamp also rejected calls to halt arms imports from Israel, saying the Netherlands prioritised domestic and EU procurement before sourcing from third countries.
However, he said the Netherlands had already taken “significant steps” including travel bans on two Israeli ministers, adding: “This war has ceased to be a just war and is now leading to the erosion of Israel’s own security and identity.”
Outside the parliament building in The Hague, around 250 pro-Palestinian protesters demanded stronger Dutch action. Local media reported chants and banners calling for an immediate ceasefire and increased humanitarian aid.

So it is not “just” but the Netherlands continue to support it, instead of opposing it. Well, Amsterdam - The Hague only is an hour by train.
