If we wait long enough to see the population ratio swing into their favour, we will see more problems. US is lucky, the population ratio of western christians/atheist and whatever beliefs in USA are higher than the muslim currently living in USA and the numbers of immigrants going into USA. But in Sweden, their total population is 5 million, which wouldn't take much immigrants to actually swing things into their favour. The problem is that a lot of justice system in the westernized world is basically based on the biblical idea of moral values set by Moses and Jesus. The muslim world do not like that type of justice, they prefer their own sharia laws over ours. The only difference is that their sharia laws are much more harsher than our justice laws (note:I am Canadian and our laws are very similar to USA)
