That is obviously false.
Muslims account for about 6% of the European populationtoday. They are expected to make up 8% of the Europe's population by 2030. See http://www.pewresearch.org/fact-tank/2016/07/19/5-facts-about-the-muslim-population-in-europe/
In other words, the Muslim population in Europe is similar to the Asian population in the US (Asians account for 5.6% of US population). Asians are certainly not anywhere close to occuping or conquering the US.
