Why are terrorists active in Europe?

Since 20 1 1 Arab Spring, the Middle East has been in constant turmoil, and a large number of Muslim refugees have poured into Europe, among which a large number of militants have been mixed.

Since the disintegration of the Soviet Union, the traditional left-wing terrorist forces (ETA, Red Brigade, Japanese Red Army) have declined. Since the Soviet Union invaded Afghanistan, the United States has trained Islamic fundamentalist terrorist forces (bin Laden's al-Qaeda) and then trained Chechen terrorists in order to seize the Caspian oil field. After that, Islamic fundamentalist terrorist forces swept the world out of control.

With the decline of Islamic civilization, Muslims are eager to return to the most glorious era of Islamic civilization (Arab Empire), and Islamic fundamentalism came into being. The decline of Middle Eastern countries after the Arab Spring has given fundamentalism a great public opinion base.

Many Muslims who immigrated to Europe and America were discriminated against, especially after the 20 1 1 refugee tide. Many refugees and early immigrants were dissatisfied with their own experiences, so their thoughts became extreme and accepted the terrorist thoughts of fundamentalism.
