Europe's immigration approach is coming under fire for prioritizing the appearance of tolerance over actual integration, with warnings that the gap is fueling extremism.

• A 2017 warning from a Gulf foreign minister said Europe's soft, feel-good immigration policies would eventually produce more extremists and terrorists.
• The core problem is a failure to push integration: learning the language, working, following local laws, and adopting the host country's basic values.
• Europe chose to look tolerant and welcoming rather than set firm integration requirements, trying to avoid seeming politically incorrect.
• Integration historically happens when people have no other choice, not when it's merely encouraged or left optional.

Outlook: Without a shift toward enforced integration standards, the tensions tied to poorly assimilated immigrant populations are likely to keep building in Europe.
