Well I don't know how well OP knows the situation in Sweden, but on larger scale he is pretty much right.
Sweden, Norway, Denmark and Finland were extremely safe and stable societies before the massive immigration from the third world countries started 20-30 years ago. Immigration as such is not a problem, but if large part of the immigration comes from countries like Somalia, Iraq and Afghanistan there will be problems. Norway, Denmark and Finland have not been as naive as Sweden when it comes to immigration, but there are also problems in these countries. The future for Sweden looks pretty grim to be honest. Honor killings, terrorism, brutal street violence, gang rapes. These kind of phenomenons were pretty much unknown before large scale immigration started from conservative Muslim countries.
