Frankly - our 3.7% muslim minority here in Germany consists mainly of social underdogs that have problems to write their name. I know what I am talking about since we have a few of them working for us.
It might be difficult for you to understand but the probability that those idiots are "taking over" is practically not given. They are simply not enough and usually much too dumb to do something political.
To answer your next question: No they are not able to outnumber us. The muslim population has a quite simular fertility than native Germans. Muslimas found out about the miracle of birth control just as their German sisters. Their fertility is higher than theirs but only slightly and the muslim immigration rate to Germany is practically zero since many years. The biggest immigration wave to Germany in the recent years came from Russia and eastern Europe.
Putin and his friends
I have absolutely no problem with Putin. It is somehow understandable that the Russians wanted at least some money for their gas from the Ukrainians. Therefore they stopped the deliverance.
Russia is not perfect, but it is somehow a democracy and a civilized country. We Germans are their closest partners in the western world and Russia is on one hand our future treasure chamber for raw materials and on the other a immense market for our goods. If we work together with Russia it is a win-win situation. They benefit from our technology and know-how and we benefit from their resources. The best possibility to export freedom is exchange and business. The western system is attractive enough to sell itself if educated and civilized people like the Russians get access to our ideas. Since we exchange ourselves with them we infiltrate them with freedom at the same time. This is much more effective than unpleasant wars.
