Remember that for every person who gets up from their arses and actually attends a demonstration like this there are a lot of others who agree with them but just don't go there, especially if like in this case they have to go to a different city to attend the demonstration.

So 200,000 people in a country of 18 millions attending a demonstration in Amsterdam only for something which is not even going to bring them personal benefits (so it's entirelly about Moral and Ethics) is yet another indication that Public Opinion in Europe is massivelly against Israel.

Yet politicians in Europe do just about everything they can to support Israel.

Now, Israel specializes in hacking smartphones and digital espionage in general, plus they were involved with Epstein and his massive international pedophilia operation that targetted VIPs worldwide.

Further, the later Neoliberal era seems to have a lot more corruption in politics than before and a lot more normalized (now generally of the "politicians 'by any amazing coincidence' retire from power straight into millionaire non-executive board memberships in companies they helped when in power" kind, rather than the good old "brown envelopes stuffed with cash") even in countries which used to have a history of being cleaner than average.

So it's quite likely that a lot of European politicians are being blackmailed by Israel after the latter gathered lots of kompromat on them via their digital hacking and surveillance operations and in some cases even via their pedophile honeypot operations.

Certainly that would explain the desperate support for Israel by European politicians in countries with Humanitarian traditions which are directly against the murderous ultra-racist actions of Israel.
