Raven, I will give you my opinion based on my being from Europe.
This is on the short side, but it will give you the idea.
After the war there was a severe man power shortage. Labor laws, along with a lot of other laws, were changed. This brought an influx of Turks into Germany and Austria. The governments that were installed were a bunch of pansy ass pacifist. Now they have a huge populatrion of Muzlims that they are scared shitless of, so they are doing everything in their power to keep them happy because they know there are terroist cell opperating in their countries and don't want anything to happen to their people.
France, well France is France, but they also have the same issue with the Algerians. Spain with Morrocans etc.
It comes down to saveing their own butts. The problem is, as Chamberlin found in the '30's, appeasement will only go so far and soon enough they will get a wake up call. Until then, it will be more of the same crap.
