Why do Europeans want Arab immigrants?

First of all, it is not "introduction" but "acceptance". Introduction is active and acceptance is passive.

Historically, Arabs are inextricably linked with Europe: when Arabs were strong, the Mediterranean Sea became an Arab inland sea, and less than half of Europe was occupied by Arabs. When Europe was strong, it turned most Arab countries, especially North Africa, into colonies of European countries. Therefore, this turmoil, war and colonization in history have caused a large number of Arabs to settle in Europe.

Later, with the developed economy and high living standards in Europe, more Arabs came to Europe with their relatives and friends.

In recent years, wars have been raging in the Arab region, and a large number of refugees have flooded into Europe. First, Europe is close to them. Second, Europeans' self-proclaimed values make it impossible for them to refuse refugees.
