I suspect a lot of the influence of Israel and the US on European politicians who again and again act against the European Public Opinon and in favor of Israel and the US, is the ton of blackmail material those two states have gathered on politicians the world over in the modern era of digital communications mainly via American systems, using portable networked pocket computers running OSes from American companies and which have everything needed to be a fully-features surveillance device, including a camera.
Every single vaguelly criminal or even just shameful action of any European politician with a chance of reaching a position of power, done via or around a smartphone or computer running an American OS and/or using American chat software, is almost certainly stored in a database somewhere.
Certainly that would explain A LOT of what’s going on in European Politics, especially when it comes to Israel turning full-on NAZI whilst European governments mainly just make believe nothing is happening or propose purely symbolic performative measures with zero effectiveness in stopping the Genocide.
