Yes Frau Merkel did make an open invitation (foolishly as it transpires. Something which I think even she now admits). But the invasion was under way long before that and her invitation was part of the hysterical reaction to the picture of the body of a small boy washed up on a Greek Beach. (You may recall he and his family were billed as “refugees fleeing war-torn Syria” when in fact they had lived quite safely in Turkey for more than three years. They had a house, the father had a job).
There have been numerous articles about Sweden over the past week or so. Here’s one from the Grauniad (not known for its rabid right-wing comments):

The article (not surprisingly) focuses on the worrying (in their view) rise of the Sweden Democrat Party who now hold the balance of power and who are vehemently opposed to unfettered immigration. However, a few extracts to save you reading it all:
“There are now more than 7,000 applications for political asylum a week in Sweden and the system is almost at bursting point. There have been small riots in Malmö over the demolition of a migrant camp set up for Palestinians and a general sense that the fabric of Swedish society is under strain.”
“There is also a perceptible weakening of support for the policy of unrestricted immigration for anyone who can make it across the EU as far as Sweden.”
I’m glad you find such mass movement of people fascinating. Perhaps the people of this village may share your fascination (or maybe not):

Of course eventually (if and when the influx ever abates) the situation will “normalise” (i.e. people will get used to what has been foisted upon them). But the question is why should their governments treat their requirements in such a cavalier fashion?
