Muslims don't do much of anything bad in the US. It seems like they do some general crime in Europe.
They seem to be leaving the Middle East and primarily going to Europe.
The reason why they're leaving their countries is because the US and Israel have been attacking their countries and killing them for decades.
If peace can be established in the Middle East, all the trouble making Muslims in Europe can go back home to where they were, and we can go back to giving zero shits about what they're doing in those countries.
Core point - Muslim problems are all caused by US / Israel warmaking.
