I didn't think I'd ever quote Putin ....
but here I am doing it ....

On February 4th, 2013, Vladimir Putin, the Russian president, addressed the Duma, (Russian Parliament), and gave a speech about the tensions with minorities in Russia:
 

" .. "In Russia live Russians. Any minority, from anywhere, if it wants to live in Russia, to work and eat in Russia, should speak Russian, and should respect the Russian laws. If they prefer Sharia Law, then we advise them to go to those places where that's the state law. Russia does not need minorities. Minorities need Russia, and we will not grant them special privileges, or try to change our laws to fit their desires, no matter how loud they yell 'discrimination'. We better learn from the suicides of America, England, Holland and France, if we are to survive as a nation. The Russian customs and traditions are not compatible with the lack of culture or the primitive ways of most minorities. When this honorable legislative body thinks of creating new laws, it should have in mind the national interest first, observing that the minorities are not Russians. .. "

 
Now don't call me a racist:
I think this should apply for Germany, too.
Sadly we are on a different path ....

What Putin actually said at a January 2012 meeting of the Board of the Federal Migration Service was:

" .. We must create the conditions for immigrants to normally integrate into our society, learn Russian and, of course, respect our culture and traditions and abide by Russian law. In this regard, I believe that the decision to make learning the Russian language compulsory and administer exams is well grounded. To do so, we will need to carry out major organisational work and introduce corresponding legislative amendments .. "
