Well, unless they start deporting now, its to late. Angela Merkel opened the floodgates back in August. In 10 years time, If family reunification is counted [and it should], there could be 20 million Muslims added to Germanys population in just 10 years [Germany has a total population of 80 million today btw]. And that is a low ball figure, my opinion is the migrant issue is just the tip of the iceberg and its never going to stop unless all borders are fortified and people are sent home. The population growth rate in the 3rd world is ridiculous [most 3rd world nations double their population every 22 years] and with Europe waving free handouts, and promising the economic-migrants a free home/car...Those people will try and move there.
And the 20 million number is just for Germany btw. It doesnt count the people moving to Sweden, Italy, the UK, France etc. Europe is being colonized, thats all there is to it.
