Answer: Europe fell into its own trap: a natural historical anti-Semitism pushed Europe into an alliance with the Arab world against Israel. The main thing—being against Israel. In addition, it allowed access to oil, markets, and security from Africa and the Middle East. Europe adopted the conditions for recognizing the PLO and the legitimacy of Jihad against Israel.
This made it possible to disguise its anti-Semitism through defending the just demands of the Arab peoples. So, out of their hatred towards the Jews, they got closer to the Arabs who have transformed Europe into the East.
