Oh it would be nice ~ but let's not forget that nowadays the Germans have a huge problem with Portuguese and Spanish migrants ~ not to mention Romanies.
Just like the 1930's, now how did they sort it out then? 
I'll tell you how they 'sorted it out'

They faffed about in exactly the same way as we are doing right now, until things got so bad as some BNP fanatic got the vote because he promised some answers when everyone else was just wringing their hands.......
Can't quite remember the guy's name - it'll come to me..... History has this way of repeating itself. Desperate people end up doing desperate things, Sure, they regret it later. But what the hell... Some people got rich!
And in fifty years or so, they will be teaching the kid's about the British holocaust. They will, of course, have quite forgotten about the German one.
