@mysteryman,
In that case the principle of cause and effect would effect all Europe, the USA, Russia and ... and ...
I lived under the after effects of the principle "
cuius regio, eius religio" (Augsburg, 1555), under the "
Principal Conclusion of the Extraordinary Imperial Delegation", and some other historic treaties, wars, rulers quite more than under under the after effects of the Nazi rule.
What I mean is that certainly everyone can write, comment, criticise, speculate etc about such without living there, having felt some "effects", and so on.
Sorry, since this has really not much to do with illegal immigration in the USA (though perhaps a bit with that in Europe).
