I'm not disputing the fact that you've never given up your claim on Israel, nor I'm disputing the right of anybody to exist. But, although the arabs who were previously living over there have never been a nation, I don't think that displacing them (in part or in toto) and occupying the land that, for any reason, they thought it was theirs, has had a good effect on their mood.
Needless to say, whatever claim they may have, it doesn't justify the use of terrorism on their part. On the other hand, if kids start throwing rocks and you blast them with tank fire, it's not exactly polite.
But back to Europe.
European countries have been subject to a flow of immigration (legal and illegal) from other european countries and from non european countries . The main reason for that, I suppose, it's economical. People trying to move to places where they may enjoy better life style, earn more money, and so on. Since in Europe we do have freedom of religion, freedom of association and so on, it's normal that the immigrants (part of which eventually become citizens of their host countries) are allowed to pray whatever God they may like. it's normal as well that they bring part of their culture in the host countries. If this is not in contrast with the laws of the host country, I don't have a problem with that.
And I don't think the fact that in Saudi Arabia christians are not allowed to pray their God is an excuse to do the same in Europe.
As for the demise of my society...well...in the middle ages parts of Europe were invaded by muslims (and by anybody else as well), in some parts there was also a somewhat pacific co-existance of christians and muslims (like in south Italy during the reign of the Emperor Frederic the second), in other parts there was no co-existance. Still, most of the countries in Europe survived, evolved and ... eventually here we are today.
