It amazes me that people think this scenario of Muslim armies invading and conquering Europe is even slightly realistic. Of course that doesn't mean there won't be terrorism. But military invasions are a complete fantasy. This particular fantasy is something I see frequently among US conservatives.

I think it is worth pointing out that the Islamic State only came to power due to previous Western attempts to "stomp on" Muslim countries--the invasion of Iraq and attempts to destabilize the Assad regime in Syria.
