And actually, this idea is nothing new for Putin, as we see in this article from 2010. Putin at that time bemoaned the 'barriers' between the EU and Russia and expressed hope that they could be removed, to allow for 'integration.'
“The main one of these [barriers] is the visa regime between Russia and the EU. We think that allowing visa-free travel would be the beginning, rather than the completion, of real Russia-EU integration.
So, how about the idea of opening up the EU to free movement of Russians or opening Russia to those from the EU? I suppose for the WN, this is perfectly acceptable. I have heard a lot arguments from this group in favor of Eastern European coming en masse to Britain and Ireland; after all, they are the same color, so why should they not be welcomed as brothers?
While I certainly believe that all people of European ancestry should be allied, especially as we are all 'in the same boat' as regards being replaced in our own countries, I believe each ethnicity should ideally be self-governing and sovereign. It may not yet be practicable, but it should be the ideal state. To believe in a pan-European 'nation of nations' is just another version of what pre-1965 America was; we were all supposed to be one nation, indivisible, despite having come from many European nations, some of which had histories of mutual hostility. We see how that has worked out. More than ever, various ethnicities who had lived together in some degree of harmony in this country, are at odds, and old grievances are stirred up, as in the instance of the anti-Anglo-Saxon grievance-mongering that has become fashionable in recent times.
The fact is, too, that the 'civic nationalist' umbrella under which we Americans co-existed for a while led directly to the proposition nation idea, which in turn has led to multiculturalism and the idea of regional superstates like the proposed North American Union and the EU.
Even if we reverted to the pre-1965 status quo, we would still be at risk of future balkanization, as people are now less likely to put aside their ethnic allegiances in favor of some kind of civic allegiance. Old animosities are re-kindled and each group, overtly or covertly, tries to gain the ascendancy against the other groups.
Bringing large numbers of Russians or other 'Caucasian' peoples into Britain would be a bad idea. They may look similar (although to me, there are obvious differences) but culturally, historically, temperamentally, there are marked distinctions. And no matter how compatible these people could potentially be (according to the Russiaphiles) the net result would be to further undermine traditional Britain, and to weaken whatever social cohesion still exists there in an already divided nation.
